4:11 posi
Any interest in a 4:11 rear from an 87 IROC? I am putting a 9 inch in my 87, and will be selling the 10 bolt. I haven't removed it yet, but will do so if theres any interest in it. I was told it was heavily modified to work behind the 383 stroker. I can pop the rear cover and try to see whats inside,but if theres no interest, I'll leave it together until its out. It works awesome, and isn't noisey. Lower stock control arms, torqueshaft, and disc brakes will be sold with the rear as I'm going to Spohn tubular. I am located in No. IL. Because there's supposed to be a price, I'll say 500.00, but would consider real offers. Thank's, Bill.

Re: 4:11 posi
I've tried to upload pics, but to no avail, somebody? In the meantime the info on the 4:11 posi is as follows, Richmond gear 80-0466-1, I09-8260. The posi is 06-13-177, 371 BC 010. It has Blue and yellow paint on the body by the springs, and white springs, also an orange dot on the ring gear side by the bolt heads. Not sure if it an Eaton, or Auburn, appears to have 4 springs, but only 1 hole I the body of the posi unit. pass. side has a flat cap bolted to it. Some are I piece casting, this isn't.Any avail. info is appreciated. Thank's, Bill.
