so here is the deal. my 82 z28 has work done onto it, and i want to know if this is something else that was done before i got the car; the rear end is a 10 bolt with 3.45 gears. is that stock? if it is, what is the quality? thanks a lot.

 

Here's what your car was originally equipped with, but after 20+ years what your car has is anyone's guess:

i understand all of that, but the thing is, there are no 3.45's listed anywhere. the only thing i could find is that it had to have come out of a ford rear end?

 

no ford rear gears will bolt into a 10 bolt. 3:45 is a 9 bolt ratio

sure its not 3:42?

positive its not a 3.42
haha, once i get back into the gears, i will check again, but i have everything written down to what it was exactly and its a 3.45 ha

 

Tyer, look on the bottom of the rear or under the "pumpkin", does it say borg warner? if so, someone swapped in a 9 bolt down the line.

 

Easier to simply count the bolts.

its a ten bolt for sure, when i did gasket work, i made sure to get the right gasket, chevy ten bolt. this is some crazy stuff.. regardless of being able to identify the gears, i love them. i would tell you when it shifts and what rpms, but im short all my gauges haha.

 

The 10-Bolt FAQ will explain how to identify what gears you have, if you're really curious.

There are no 3.45 gears for the 7.5 10 bolt. It has to be a 3.42, or it's a 9 bolt, or you figured something wrong.
