1970 Esprits with factory installed 400 motors ALSO got a 12 bolt as standard equipment.
I believe your 10 bolt non-ac 350 should have 2:73's |

This car would have an 8.2 chevy rear. Pontiac didn't build their 8.2 for the second gen cars since they knew the 8.5 was coming in '71...

my friend got the car home today and snaped a pic of the rear. it's a 10 bolt with the posi tag around the fill plug. about 2.73 gear. not a pontiac style cover, or a 8.2 chevy cover (that i'm familiar with anyway). it also doesn't have the "ears" on the bottom like an 8.5 does. is this what an 8.2 chevy style rear looks like in a 70 Espirit?
the more i look at the pic, the more it looks like a buick/olds 8.5 12bolt to me. don't the bottom 2 bolts look more side by side insted of 1 in the middle like the typical 10 bolt? Last edited by Matt Meaney; 01-18-2009 at 07:46 PM. |

Yep, I was pretty happy when I saw it had the 12 bolt.
My son and I just put some 4.10's in it with a posi this past summer.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
