Dumb question about IRS

[synoptica]

Hey guys,

I'm almost 100% certain that this is a no - given that I've not seen it done before - but can a VP IRS diff be bolted up behind an earlier non-IRS model?

Or, rather, why can't it be?

Cheers,
Chris.

It can be done but at a cost

Well - exactly what's involved? Can an IRS rear axle be bolted in? Where does it differ?

Well I reckon you need to make the rear floor pan stronger to bolt in the main part of the diff.
Also i think you might need someone to make new trailing arms. Also you can get a top notch engineer to make new drive shafts at your length.
