Hi everyone.
I've a Euro and USA 1980 model w/o LSD.
I've found this:

I'm a not great expert, better a noob, so someone say if I could put it in my rear differential and have so finally the differential LSD?
Thanks a lot!

 

I think that's all you would need to get lsd, but that auction has ended. In my opinion, it would probably be a better move to find an entire rear end from an 83-85 GSL. That will give you the lsd, disc brakes, and you'll keep the same lug pattern for the wheels. I don't know how available used parts are in Italy though...

 

i think too, but it's too expensive from USA...
Thx a lot!

 

I've a little more time now...
So kentetsu you think it could be fitted in my rear axle? The seller told me it wuold not fit in 80 model, but here I had also read pinion is smalle until 83 right? So must be ok in my opinion...
Thanks to any other could give me some info

 

Posi diffs didn't show up till 81. Afaik, there are only 2 general versions of diffs. S1-S2 are small axle, S3 are large. See no reason why it wouldn't fit.

 

Setting up a rear axle after swapping gears is a bit touchy if you haven't done it before. That's why most people prefer to buy a complete assembly.
