[gp02a0083]

there is a tag on the trunk of a monte ss that is code for the rear and stuff. google it. it will save you some time. not all monte SS's were posi

look for the code G80 , that's a posi code on the sticker

I wouldn't trust the tag on a car that's decades old, who knows if the rear end was swapped out for something else...

And you can't be sure that its the same trunk lol. Like me, car had no trunk Popper, but the trunk that's on there had a solenoid. So It has codes for the car it came from haha.

Yeah, When i went and looked at the tag on the truck it said i had the 3.73 gears non posi and when i actually counted the teeth and divided it, and it came out to be a 2.43 or somthing like that not the 3.73s.

there is no need to count the teeth, the number of teeth on the crown and pinion are stamped on the crown gear and you divide those numbers to give you the ratio
