hey i have a 1986 camaro and up until now i thought i had a 9 bolt but someone said i have a 10. can someone help me out. http://i205.photobucket.com/albums/b.../9boltor10.jpg thats a picture of it next to a 9 bolt and 10 bolt gasket

 

No plastic drain plug means its a 10-bolt. Count the number of bolts holding the cover on. 9 bolts means its a 9-bolt rear and 10 bolts means its a 10-bolt rear. That is where they get their name.

 

i know but i have no way of doing that. i dont have a jack to put it up , and i cant fit under the car to count

 

Well, what do you suggest then?

If you dont have a jack, get your digital camera and start taking pictures from different angles and see if you can count the bolts

 

I'm sure you could find some wood to back it up on

No Jack

Later

 

if the pic is your axle, its a 10 bolt

 

yes that is my axle but are you positive???

 

I personally would never do that, as I had a friend killed using wood to support his car!

 

Positive. Like stated before, no drain plug means it's a 10 bolt. 9 bolts weren't availible in '86 either, assuming that is the original rear.

 

I'm positive YOU need to find a way to verify. This isn't rocket science.

I would agree with the wood statment, but if you get some 2x (at least 2x6)somthing that you can back the car onto, use them like a ramp you will be fine. Just don't be stupid about it. If it's a clutch use chock blocks.
If the top of your driveway if flat then it angles down back it up til your tires are on the edge of the flat part and the back hangs over the angle, then look. (more clearance)

 

Actually yes they were available starting in 1985 on Trans Ams, and in 1987 on IROC's. But since the car in question is an '86 IROC, yep, it didnt come with a 9-bolt rear.

What do you mean you cant get under the car? My car is lowered and I can still look under the muffler and see the rear end and count the bolts.

 

what is the big difference between a 9 and ten bolt anyway i found out today i have a 9 are the worth anything it has alluminum calipers thanks

 

The 9 bolts are a little stronger than the 10 bolts, and most of them came with disc brakes. They have a 7.75" ring geat rather than a 7.5". Other than that, there's not much difference. They are hard to find parts for, but 10 bolts are a dime a dozen.

 

Depending on the gear ratio, the rear end, especially with the PBR's, is desirable.

it has 277 in the rear also internally are they the same like ring and pinion size
