Everyday Performance LLC has 5 Buick 10 bolt 8.5 cores that need to get built and sent on their way. These are the 10 bolt 8.5 A body rears with bolt in axleshafts I am currently building one as a 3.73 and another as a 3.42, both posi. I can build any ratio you need. All new bearings and seals, new posi unit, new gears, new control arm bushings, new vent. Limited time offer, call to place your order 860-218-5780 prices vary depending on build, but regular price $1550, now $1450
The 3.42 rear was strapped to a pallet and is on its way to a new home! Up next, I am building a 3.73 posi rear, and then a 3.23 posi rear. Lets make a deal!
The 3.73 ratio posi rear has been sold. Currently building a 3.23 posi 10 bolt 8.5 BOP rear. For sale now at the discounted price! 3.23 is a great ratio for performance with a three speed transmission like the TH350 or TH400. Then I have one more core to build and sell.
Sent a 4.11 spooled 8.5 down the road a week ago. 3.23 posi 10 bolt 8.5 rear, completely gone through, is still available. I have one unbuilt core remaining.
