I have a 7.5" rear diff which I want to mount on my 4wd saph cosw rear end, is it possible using the 2wd rear drive shafts or won't that fit the rear arms ?

Thanks for your help !

 

Yes, but you will need to change the stub axles as well for 2wd ones, bigger C.V joints !

 

..and I understand that you will have to grind some of the mounting lugs off to get in to sit in the 7" beam fitting.

 

not just that, the pcd of the 2wd diff is 108mm
the pcd of the 4wd cars is 100mm

so none of the holes line up as the cv's are different sizes

easier to just get a 2wd rear end set up in the first palce than have to chop the 2wd diff about

 

Yes, the diff has 108mm PCD, but would the driveshafts fits the arms if I use 2wd driveshafts with 2wd stub axles ?

 

Hes talking about using a 2wd Diff and 2wd driveshafts , as long as you also use the 2wd Stub axles of course it wil fit !!!!!

 

Yes that's the confirmation I wanted, thanks mate !

 

Matt I'm running a 2wd beam, stub axles, drive shafts and diff.
4x4 arms and 4x4 arb to suit the arms.
