10 bolt 8.5 differential open to limited slip
Would like to replace the open carrier and 2.73 gears with a limited slip carrier and 3.73 gears for my 1972 cutlass. Is this possible using the original housing?
When I took the housing, new gears, carrier and rebuild kit to a local mechanic (who has had experience rebuilding differentials for the circle track)... He said that he has run into situations that the limited slips would not fit into the old housing.
Information either way would be very helpful.
Thanks

Find a new mechanic. Your '72 has an 8.5" rear. Any 8.5" posi from 72 through at least 87' will work. You will need the right carrier for your gear selection, I believe it has a #8 on it. I have had the best luck getting them out of GM station wagons with a tow package. Jkaz

Hey Gearheads.....need your help too, please.....
What is ROP? New one on me. Maybe my brain's not in gear. I also want to change my gears to 3:23 and put in posi. Did you go with AUBURN or EATON? Can't remember off hand whether it has to be a series 2 or 3 carrier. But, I do remember reading somewhere that GM stock posi carriers weren't as durable??
How's the 66 project car coming along? Haven't seen any pictures of it for the longest time. I know that it's probably a money or time thing. Got anything for those of us who are curious? It was looking really nice.
I just did the exact swap with no issues. I suggest looking up Brian Trick on ROP for the carrier. He had the best price.
