Its a 71 skylark with the 8.5 rear. It has 2.73 gears in now and I am installing 3.42. Do I need a different carrier?
Thanks for the info. Im thinking about installing a full spool. Will the spool have the correct offset or will I still need a spacer?
NO you do not . 2.73 -5.57 is on the 3 series carrier 2.41 -2.56 is the 2 series carrier PLEASE disreguard the info you just received. 10 bolt 8.5 has a different carrier break than 12 bolt chevy and 8.2 chevy 10 bolt 7.5 AGAIN is not the normal carrier break either. it is as follows 2.14-3.08 2 series carrier and 3.23-4.56 is the 3 series carrier. Just install your 3.42 directly onto your 2.73 carrier and you will be good to go. Take care, Jim J D ---------- Post added at 03:46 AM ---------- Previous post was at 03:43 AM ---------- Full spool is for RACING... You will need aftermarket axles too If your car is 50 / 50 still go posi NOT SPOOL. The spool only comes in 3 series which is any ratio from 2.73 -5.57 and all in between.
Crap as always Jim is correct about the 2.73 being a 3 series posi. I keep forgetting that the 12 bolt is different than the 8.5 sorry
Thanks for the info guys. I hope I will have time to put it back together this weekend and try it out. Have a good easter.
Cars back together and works great.:3gears: Does anyone know what size (# of teeth) speedo gear I need for the 3.42's?
