Goin' POSI - Locker questions...

[Junkyard Dog 32]

If the H.A.M.B. Drags tought me anything, it's this:

I NEED POSI.
If it ain't hookin' up, it doesn't matter what you got.

So, I came home and started askin' around.
This is what I found.
I'm told it's Auburn, and it was in a mid 80's Monte SS... The rearend in my deuce is out of an early 70's Firebird (10 bolt).
There was no ring gear on it. Will I be able to use it, and will my ring and pinion gears work?

I traded an old shotgun for the locker and $100.
What might it be worth? Just in case it won't work and I end up selling it.

Thanks,

Do these numbers mean anything?

H7 2 ----> <---- 72

The monte rear is likely a 7.5" ring gear, the one in your car is likely to be a 8.5" ring gear. The unit will not work if this is the case. You should be able to find a posi unit for an 8.5 relatively cheap. GOOD LUCK

either swap housings for and s10[4 wheel dr] [is wider than lil 2 wheel ones]or go to 9"ford and beef it all up.

Well I don't know for sure about the Monte SS's, but Grand Nationals came with 8.5" ring gears. If you've got an 8.5, it'll handle some shit, but you might wanna put stiffer springs in it. If it's a 7.5", (which came in the stock montes, regals, and about every other car, s10, or astrovan made since 76 ) You got screwed. I puked 3 of em in my 14 second Malibu when I was in High school.

BTW: It's a "limited slip", not a "locker", BIG DIFFERENCE
