Front guards on a Mk2 Escort are spot welded on from the factory. If I were to bolt them on using rivnuts and M6 bolts every 60mm or so (for ease of panel gap adjustment/removal for future repairs etc) would this get into certification territory? 

My thinking was that people have run fibreglass guards on Escorts for decades, and given that they predate any kind of frontal impact legislation it might be allowable - the bolts are spaced at roughly the same intervals as the spot welds were, so whatever body stresses the guards carry should be unaltered. However, the bloke painting the car reckons otherwise, and tbh looking at the VIRM it may be classed as a modification to the vehicle structure.

Who is right?

technically it would need cert, as it is a structural mod due to the guards not being welded on any more , even if the guards are not very structural 

 

Depends how legal you want to be I guess. If you need a cert for other mods it would be easy to get that certed at the same time

Cheers for the speedy reply! The car is standard otherwise, so maybe this will be the tipping point for more mods...

Or maybe I'll ask the body shop to just weld the guards on. It would probably take a fairly observant WOF inspector to notice the difference, but why risk it tbh.

I'd just weld them back on, not worth going through the cert process for that. All of a sudden there is a big list of requirements the car will need to meet. No cert = no worries. Guards will be good for another 40 years i'm sure.

Diff stub axils. Can the axil mounting flange be cut off and a new one welded on them machined to suit different axils? 

Diff in question is a Nissan LSD unit to go into a celica.

So you are talking about an IRS center and just modifying  the drive flanges on the diff?

If so I think you would be ok cert wise as nothing really bad would happen if it broke, unlike a solid axle rear end where the axle can come out if it breaks in some situations

Thanks Clint. Yes an IRS Center. Sorry I should have clarified that.

Also can I redrill a new pcd on the diff input flange? It currently has a 4 bolt pattern and I need to drill a smaller 4 bolt pattern. Will align the new pcd between the old.

Will also machine a ring to locate the driveshaft into the spigot on the diff flange.

Would it not be a possibility to get CVs from a Nissan that the cups fit the Toyota half shaft? 

????

It’s Toyota driveshaft and axils getting mated to the Nissan diff. Are you meaning if that Toyota inner cv was replaced with the correct 5 bolt Nissan unit that happened to also fit the Toyota spline on the axil?    Or combine a Nissan outer cv shell with Toyota cv guts?  Could be possible but we also need to narrow up the diff as much as we can. Nissan is about 80mm wider than the stock Toyota.

Also not mine to do the required research and the work asked above is all easy to do.

Stock Toyota on left, Nissan on right.

Either option but I was specifically thinking of the Toyota guts inside a Nissan.  Given you (or whoever) have to modify the length of the shafts then I would have thought up sized and custom shafts may be a better option given the power increase being sufficient to up rate the diff, not upsizing the half shafts seems a bit..  Odd. 

Ditto for up rating the drive shaft with bigger ujs.

Ah yep I see where you’re coming from.

I’d imagine the half shafts and cv’s will be fine, if anything the driveshaft and uj’s might want to corkscrew.

It’s a street car so won’t get a real hiding.  Or should I recommend he runs supercats, linglongs or equivalent :)
