Popular Post kp60nick Posted October 5, 2023 Author Popular Post Share Posted October 5, 2023 So you guys must be sick of c notch updates but for something that seems fairly simple. I wanted to make sure I do it right. So here (thanks to my neighbor Danny) the notch is hopefully set in the final place. I've been waiting for the two 6mm plates that slide on the bar and finish off the bag plate. I will be cutting the crossmember tubes shorter. =) Ive been waiting for everything to come together to check this space between chassis rail and top link. Thank god it seems to have ample clearance. 11 Quote Link to comment Share on other sites More sharing options...
kp60nick Posted October 5, 2023 Author Share Posted October 5, 2023 This was also a purchase I made over the weekend. The are very rare for a d21 so I was very happy to get my hands on it. Factory tinted glass too. This means i will probably need to tint the two rear side windows to suit. 6 Quote Link to comment Share on other sites More sharing options...
Popular Post kp60nick Posted December 21, 2023 Author Popular Post Share Posted December 21, 2023 Finally picked up my balls! C notch is welded (sort of) chassis is cut, 4 link arms, brackets, bag plates, more tube for crossmembers and 4 weeks off work have all been acquired. Time to smash all that together and see what I can create. I purchased my 4 link arms from rod ends nz. I Was very happy with their service. At my door the next day.

Popular Post kp60nick Posted January 29 Author Popular Post Share Posted January 29 Over the break I got some time to work on this. First thing was to clean the chassis rails as I needed to make a crossmember for the upper links to attach to the chassis. Got the leaf spring mounts off the chassis pretty easy and clean. Next up was to fill a few of the holes in the rails as the mounting for the crossmember plate was going to end up half over them. Ended up putting a bit of 3mm plate in the drill press and got a hole saw with the right inside diameter as the hole and cut heaps of plugs. welded them up and smoothed them off. Got my domino's pizza brackets that I worked out and got cut before xmas clamped them on made sure the drive shaft at full air out doesn't hit the tube and that the angle of the top link matches my calculations. Once that was welded I was able to work out the tube the lower link is attached to. I didnt want to mount the bottom link under the chassis as I didnt feel that the bars would be long enough. Under the rail would have been around 600mm and I've gone with a 750mm to try keep the ark fairly big. So got some 44mm rollcage tube which is smaller than the crossmember tube (48mm) but only because have we only have 44 tube bender dies. Did a double bend from crossmember down to plate on chassis rail. Is a shame the driveshaft is so far offset but I cant do anything about that. At this point I was waiting for a couple more brackets from one stop cutting shop. I moved onto cleaning up the chassis rails behind the notch where the fuel tank and air tank and compressors mount. Once the brackets were ready got straight back into it and carry on finishing the 4 link. The lower bracket is probably a bit over kill and most of the holes are just for looks. But it ties the crossmember and the support tube to each other. Tacked the bag plates to the chassis inside the c notch crossmember and cleaned up the diff tube. Removing leaf spring mounts was a messy process. Once that was sorted lined up the diff in place using my jig I made earlier and tacked the bag mount to the diff and all the link brackets to the diff. Once that was done was able to bolt bags in and wait till to get some air fittings to see how/ if it all worked. Probably heaps I've missed and haven't shown any of my head scratching time or the laser cutting process. So far everything is just tacked but plan on taking body off in the near future so will be easier for someone with more welding skill than me to do that. Any questions I'll be happy to answer. I'm loving the motivation I have at the moment hope I can keep it rolling. Thanks for looking Nick 10 Quote Link to comment Share on other sites More sharing options...
Popular Post kp60nick Posted January 29 Author Popular Post Share Posted January 29 Here is the second attempt at the up and down stuff. First attempt was a flop I was using leftover fittings from the recent laundry renovations. Got some fittings and a Tap hooked up to garage compressor. Man so happy to have it to this stage. I've wanted this for a long time. I was surprised to start with as i didn't feel like i was getting enough lift but at this stage I'm just assuming that once the front goes up and down as well it will all work itself out. 10 Quote Link to comment Share on other sites More sharing options...
kp60nick Posted February 1 Author Share Posted February 1 Shocks mounted and work great in the range of travel. Had to do a bit of grinding to get the brackets to work so they didnt fowl the shock body. Next up is the air lift performance height sensors. I'm not having much luck with keeping it within the 120⁰ range. And in the manual it says move sensor closer to pivot point which means mounting on one of the arms but I cant see that working in my case as the arms are adjustable and need to spin? Or am going to have to make a tramp rod looking bracket that comes off the diff so I can mount a tiny little m5 bolt? Haha maybe a bracket that clamps to the arm that would need to be loosened if the arm was ever needed to be adjusted? anyone had such experience?

Nominal Posted February 1 Share Posted February 1 I welded mine to the lower arms, but mine have one fixed end so don't need to rotate. Something clamped on to the arms would be fine I think, there's no real load on the sensor links 1 Quote Link to comment Share on other sites More sharing options...
kp60nick Posted February 1 Author Share Posted February 1 Thank you @Nominal. 30 second google search. Equals results 3 Quote Link to comment Share on other sites More sharing options...
Nominal Posted February 1 Share Posted February 1 Better than a hose clamp which I was going to suggest 2 1 Quote Link to comment Share on other sites More sharing options...
LWL1FE Posted February 1 Share Posted February 1 Alternatively can you make an extension to fit the sensor arm to add an extra pickup point further out?" Quote Link to comment Share on other sites More sharing options...
cletus Posted February 2 Share Posted February 2 whatever you do, make sure the bags can be inflated, with the wheels at full droop, without the sensor going to max travel i think ive had 3 different cars break the arms off the first time they go on the hoist... nice work on the truck! 4 Quote Link to comment Share on other sites More sharing options...

Whaaaaat? They set the sensors up so they won't make it to full droop?? Quote Link to comment Share on other sites More sharing options...

I had one arm break like that, I guess full inflation squeezes a bit more travel out? At that point I couldn't get a new one so made one out of a bit of Al. It's still there after a few years. Maybe I extended the drop link a bit so it wouldn't happen again. 1 Quote Link to comment Share on other sites More sharing options...
Popular Post kp60nick Posted March 10 Author Popular Post Share Posted March 10 Been through a few ups and downs with this lately. Pardon the pun. Took it off the axle stands to get the full lay frame experience but unfortunately my bag mount bracket on the diff is a bit to tall. Same with the top link bracket. Unsure if it's also got something to do with the front not being fully slammed yet. But once the 15s on it sits quite healthy on the ground. Pushed outside today for a bit of sunshine. Here are the results. As far as progress is concerned there has been none apart from planning how I intend to rectify the problem. Thanks for looking. 13 Quote Link to comment Share on other sites More sharing options...
