s5 open diff to lsd swap questions.....
 

i have a 90 convertible that came with an open diff, i want to switch over to lsd, but i dont want to deal with swapping everything over. can i just put in an lsd from another n/a rear? it really dont want to have to get a new driveshaft and halfshafts. also, if i can just swap in the guts, or the whole pumpkin, i need them, so email me if you have them for sale. thanks guys.

The 3 drop-in options are (in order of MY prefrence)

S4 Clutch-Type Differential
1.8L Miata Torsen Differential
S5 Viscious Differential

Any of the 3 will drop right in.
