Someone is giving my an 8 3/4 rearend from a 1966 chrysler imperial. Does anyone know what gears it might have and would it possibly be a sure-grip. what was the most common. Ive been looking on the internet for info and cant fin any. I bought the running 440 and 727 auto from the same car. He also threw in everything on the motor and the rad and rearend. I'm hoping its a 489 3.23 sure-grip. I have a 1971 barracuda with a non sure-grip with 273 gears. It now has a 1970 340 which a will not sell. I just wanna see how it runs with the 440.

 

This might help, put it on some stands and mark the tire and yoke, count the # of tire rotations for every 1 of the yoke .... eg 3.55:1 = 3 1/2 turns to 1 - should be a tag on it somewhere ..... or http://www.hemmings.com/mus/stories/...feature21.html

 

what is that a 1971 scamp

 

Im going to pick it up tomorrow. Hoping its a sure grip.

 

I'm taking a stab its going to be a 3:23 open. May be even low like 2:7s though

 

That it is, or the Dart with the Valiant front clip as my brother calls it lol

 

i doubt it'll be a sure-grip if it is from an imperial

 

prob. not but just a matter of exchanging the carriers to make it one, one wheeler peeler with 2.76 gear is what I'm thinking it is

 

Imperials only had 2.94's through the 60's. How do I know that? I have 2 68 Imperials. Sure grip was an auction, one of my Imperials has it.

 

Turns out is not sure grip looks like tag reads 29?
