A while ago I got an LSD off an 87 T2 and the diff is in perfect working condition, however to mount it onto an 89 S5 I know I have to get T2 halfshalft and my driveshaft modified. However I bought an 87 N/A parts car still havent even started taking part off of it, but I heard they came stock with LSD's is that true? And is it a direct bolt on to an S5? I will probably go start taking parts off the car tomm...Parts will be for sale soon...

 

N/A and TII pumpkins are different sizes. You will not be able to put the TII diff into your N/A, without using the whole TII pumpkin.

But will the 87 N/A's LSD be a direct swap from that into my s5? And what you meant was putting the T2 LSD into the N/A pumpkin?

 

If the 87 N/A does have LSD, yes, it would be a direct swap, diff for diff. Check to sure it's a LSD. I'm not sure without looking at the thread at the top of 2nd gen section.

 

If the 87 is a GXL, then it had an LSD. If it was a base model (4 lug bolt pattern) then it didn't come stock with an LSD. That doesn't mean a previous owner didn't swap one in however.

Easiest way to check, jack the back end up on the 87 and spin a tire. The other tire should spin in the same direction.
