I got a customers ute through cert late last year with a pair of Ali front caliper brackets which were done by another shop. Clints initial noting on the fail sheet was that he will need to check how much they flex once the brakes were bled up. In the end they passed. While discussing my brake kits, he suggested that steel is a better option because they will likely flex less and also Lvvta are more strick with critical things like that, which are made from Ali especially when threaded. They will also need to be made from 6061-T6 and if they are threaded, I would suggest emailing Lvvta to get prior approval. I decided to use steel for the Cal brackets in my hilux big brake kits so there would be less chance of any dramas come cert time for the people who brought them. Initially used p20 but it was hard on the tooling while machining so settled on G350 for the rest.

Did you have any luck finding any? I have some 14x7 steel barrels from ford 12-slot rims, but would be mint to find some 8" or 9" barrels.

Been a while since I discussed it with @cletus for my application, but from what I remember, its more to do with the connections inside the vehicle. So if you have hose connections/clamps that could possibly break or leak, or any sort of flanged/removable connection, then there is a chance fuel vapor could get into passenger cabin if there was a slight leak etc. Which is why sealing off the boot is needed. In my case, all the fuel fittings were under the floor, but because the filler neck passed through cabin and it had 2 hose clamps connecting filler neck to tank, I had to seal it off. I could be wrong but I think we established that if I made a fancier filler neck connection under floor with a low profile o-ringed flange or something like that then I wouldn't have need a sealed off cover. But I'm not sure about whether sealing is required if you have a 100% sealed tank with all connections/fittings under floor when you do a carb to efi swap. Probably depends on how your tank is setup. If you intank pump has a flanged access point inside the boot like Kellys surge pot does, then that would likely be classed as a potential leak point.

Totally racist, need a yellow zinc to balance out the diversity.

Just claim that you are a sovereign citizen, then use lots of big legal words to sound intelligent & threatening.

^ With all the privacy laws we have, I don't see how a fulltime gps tracking system like E-road or similar for ruc management/speeding etc could be passed here for private vehicles. Massive invasion of privacy not to mention a target for hacking so crims can find/follow the desirable vehicles easier. E-road already causes big problems between staff in the workplace for company vehices, so it would be a disaster for private vehicles.

I did some work on a 323 hatch last year. Spare wheel well delete, underfloor Ali fuel tank and modified the filler neck to suit. As the neck passed through the passenger cabin I had to do what Clint described, so I put a flange on the floor and made a cover panel to seal off the filler neck. Also had to do Ali side panels as they are just carpeted from factory. You could do something similar. Its a bit of extra work but gotta do what ya gotta do really.

The Por15 and Kbs tank sealers are decent. Have used them plenty. Its best to get the tank acid/chemical stripped first, but short of that, chucking a heap of clean shingle in there and shaking the fuck out of it will get any loose shit off and key the surface. A wash out with thinners will give it a good residue free clean, then you can go through the coating process which usually have a phosphoric based metal prep as part of it.

I checked my hiace one here and apparantly it is... But yeh cast/forged possibly. I spoke with the bald jesus @cletus himself about about narrowing them that way eons ago and he rekons it was a jailable offense at the time or something like that.

Technically no if it was spotted because you are not allowed to weld castings, which is why I shorten them through the housing tubes. If you remade the flanges from weldable steel however...

Get an initial inspection done and have a chat with repair certifier to undertand the process. He will say what he wants to see and how he would like it done. He will also tell you at what stages he needs to come back for progress inspections, which will depend of the level of repairs needed. And take a shitload of photos throughout. Can give you a more detailed example of the way I go through the process if you want to pm me.

And they think a firearms register is a good idea...

Might help to make a wireframe buck/template first. Can do it with tig wire or gas welding 'panel' wire. Bend the wire to the shape you want, tape/tack weld them togethor, then you can lay paper over in sections to transfer onto Ali sheet.

Re: 620 diff. Do you recall what that 3.9 you scored came from? Thats a pretty rare find. If it was same axle spline then must have been from an old Silvia as the Fairlady Roadster and 1600 Wagons have smaller spines. If you come across another, let me know, I need one for my pickup.

Probably Takanini PickaPart. Theres a rack of them, then a shitload just scattered in the ground. Zebras selection was ok, but I havn't been back there since they reopened recently.

Is an Gtr style intercooler an option? Shorter but quite wide. Instead of having the outlets of the end of the tanks, have them exit back toward engine. Or just run a smaller one so you don't have to change piping but have a water/meth setup as backup?

You need at least 0.5° operating angle on a UJ. Lesser the front shaft angle difference the better but not less than 0.5°. Currently you are at 0°. And max 3-3.5° operating angle on front UJ out of box. Now if you raise the hanger bearing so front UJ operating angle is 0.5-1° (front shaft initial angle of ~4° down) it will lessen the centre and rear UJ angles and still be within the max 3° front UJ angle. Centre and rear UJ's still have pretty bad angles but not much can be done about that without a fair bit of rework. If you set the pinion to ~6° down (flange pointing up) it will compensate for a degree or so of bushing flex under acceleration and get you close enough to where it should be happy. Link design/geometry will play a big part in driveline performance too, but thats confusion for another day.

If the oiling system allowed it, and if I was chasing driveline perfection I would be setting the engine to as flat as possible and remaking the manifold/tunnel etc to suit. Just depends how much work you want to do I guess.

Because you have a greater angle on the gearbox than the first shaft, raising the hanger will make the operating angle of the front UJ worse and its already at 3.5° based on the angles you mentioned on box and first shaft, so wouldn't really want to go any more than that. The lower the first shaft angle, the less rotational pulsation the second shaft will have to try cancel out. The higher the rpm, the lower the operating angle should be. If it was the other way around like most vehicles, for example the gearbox was 3° down and the first shaft was 6.5° down, then raising the hanger would help get the front UJ to a lesser angle. Are you sure the box is 6.5° with carb where it needs to be? Are you measuring that off the crank pulley/sump? Seems like alot. I can't remember what the last rotary I mounted ended up being with the carb level tbh. Post up a rough/close enough angle of the rear shaft when you get a chance. I'l calc it how it currently sits and see what the pinion ends up at.

Is that laid out or at ride height?

What angle is the 2nd shaft on?

Most of the online diagrams go out the window with bagged stuff because they are geared toward the pinion being far lower than the output shaft on trans. Spicer has a good angle calc.

Go take a marketplace Hilux for a test drive and switch them out. Thats what Billy T would do.

The qd32 is just a newer big brother to the td27. Bellhousing patterns are the same and a bunch of other parts like the manifolds are interchangeable so its possible the heads are the same or similar. The 'Td27 Torque' facebook page is a wealth of knowledge so chuck up a post on there.
