I have a posi rear end I pulled out of a wrecked '87 GN years ago. I removed the lower control arm mounts and added leaf spring hangers for my S10. I then put 4.10 gears on the factory posi unit. I ran it from '95 until about 2 weeks ago on my V-8 S10 Blazer. I pulled it and replaced it with the original S10 rear end before I sell it (the S10). Now I need to sell the Buick GN rear end. I have a relitavely low price because you would need to fabricate new/re-use your existing lower control arm mounts (with coil spring seat) and weld them on. The upper control arm mounts with rubbers are still on the center section. I also robbed the brake stuff (drums, shoes, ect) to put back on my 7-5/8 S10 rear. I am sure you could re-use the lower control arm mounts and brake stuff from your original rear end if you wanted too.
Anyway.... $600 gets it shipped to your door anywhere in the continental US. Paypal preferred.
Thanks.
