If you are thinking of going back to a standard rear end, then this might be of use to you.. https://www.facebook.com/marketplace/it ... 7520233058

Every image I can find of early 3 series axles are cv joints

If the car is not complete it is not a huge deal to lift the body up. The Sierra is a nice diff, so if it can be used it would save money

Back in the day people would cut VW axles in half and reweld them shorter for Elans

I have been reading through this and you have my sympathy.

To try and be helpful could I clear up that you have universal joints and not cv joints? As per the post from Gus E31 BMW's use CV joints as per the 2nd image. The 3rd image shows a set of sliding spline universal joint driveshafts for an Elan

Hi guys
Thanks so much for all the help - just to clarify, the shafts have universal joints(I was under the impression they were from a bmw E21 Could be wrong. The main problem is the UJ binding / locking because of the angle, so by what you are saying a cv joint is the way to go and keep the Sierra diff. I like the idea of modifying vw shafts. Again, thanks for all your help, this is a brilliant forum

Notice on the Kelsport uj driveshafts that the shafts are sliding spline. If yours don't have this feature, then they will almost certainly bind at anything more than slight angles.

BMW E21 used CV joints if you have UJ on the drive shafts i.e. Hookes joints then you also need a sliding spline to accommodate length change , do you have that ?

UJs may bind at a much lower angle than Cvs. Also if you have Cvs the length of the shaft may be wrong so that the length travel of the CV is exceeded.

How you fix what you have at lowest cost may be very simple or very hard. More detail and some photos would help

cheers
