Is there a way to tell the difference between an 8.2 and an 8.5 posi carrier?
With all the swap meets out there a lot of the carriers are just sitting on a table or the ground.Would there be a sure way to tell by looking for casting numbers and where would be a good reference chart? Also can you determine if the posi unit is damaged and what would be a fair price for a used unit?
I am intrested in a rebuild of my 10 bolt but being new at this it seems a good start is to ask a lot of questions.
Thanks Paul
If there is still a ring gear bolted to the carrier, take a look at the size of the bolt heads. If not, look at the size of the threaded holes for those bolts.
The 8.5" 10-bolts use 7/16" left-hand thread bolts. The heads take an 11/16" wrench/socket.
I believe the 8.2" 10-bolts use slightly smaller 3/8" bolts that take a 9/16" wrench/socket.
Thanks for the info Ray,
I guess a good idea would be to carry one of each size bolts and try them at the swaps, being that 3/8"thd and 7/16"thd are so close it would be difficult to determine the actual size by eye.
Thanks Paul
Sorry to bring up an old thread but i figured id ask here instead of opening a new thread. I have an 8.5 10 bolt but my ring gear bolts take a 3/4 wrench on them instead of an 11/16 like i read here and other places. what does this mean?
I have the same as mike, according to this thread its posted that the bolts have a 11/16 head, mine are also 3/4 , all the other casting marks and cover size matches the post, any input from the Guru's out there? 72 nova stock with an l6, soon to be different lol
OK, feelin a lil stupid, further research and pulling the carrier its a 8.5, the 3/4 head is an industry standard "heavy" as they call it,
