Richmond 4.10's 10 bolt rear set number 49-0009-1.

My car is an 88 Iroc with the original 2:77 rear end.

Will these work with the posi carrier from SLP?

No and again No. If you have a 2:77 rear now, it is a BW 9-bolt and the parts you quoted are for a 10-bolt rear. The Parts are NOT interchanable, sorry.

Sorry...I didnt even know if mine was a 9 or 10 bolt.

Can you suggest what to do?

I desperately need to get the crappy 2:77 out of the car.

So youre saying the carrier from SLP will not work in my rear end either?...or will it fit, but just not with that 10 bolt gear.

You have to get a series 3 posi carrier and gears for a 9 bolt borg warner 7.75" differential. The SLP stuff will only fit a 10 bolt rear.
