Good afternoon everyone! I just picked up a rear end out of a 69 Hurst olds with the "SL" stamping on it which should be 3.91 posi correct? Second question i think the 3.91's were optional, does anyone have any information on how many 69 hurst cars came with 3.91"s. Just some food for thought.

 

3.91 was an option for non A/C cars, 3.42 being standard for non A/C cars, 3.23 for A/C cars. Unfortunately I have never heard or seen of any breakdown of how many cars received which options.

 

I have one and Bob Anderson has one

 

Bob Anderson has had a lot more than one.Did you ever see his starage facitly with cars stacked on top of other cars,crushing the one on the bottom?It's sick.
I had an SL 3:91,which is now in the hands of Dan Macal.

 

No I have not seen it I know one of the 69 h/o he has was a local car Bruce bisping sold to him at the olds nats years agoe .

 

I havent yet messed around with different gear ratios (as this is my first build) i am pretty excited to get that diff under the rear of my car. Should be a substantial difference from the ol ope 2.78's!!

 

Just ballparking it what does an SL rear end like ours go for?..........not that mine is for sale, but out of my own curiosity i suppose.

 

I sold mine,completely restored,for $1200.00.It was flawless.
