Folks,
I am looking to buy an 8 3/4 sure grip with 3:55 (or 3:73 not sure if Mopar makes these) gears. I prefer a 489 case however would not mind a 742.

I currently have a 742 case. Previous owner tells me it has 4:56 gears and a strange spool. Drives like 4:56 gears however not sure if it is a spool (They both definitely spin), will need to wait till disassembled know know for sure.

I would be willing to trade/partial trade for this if need be.

I am looking for reasonable prices

3.55 or 3.91 were the factory choices.

 

And 3.23's




Nope, no factory 3.73s

 

I was curious on this issue, GM world has the 3:73's and seems they would be a good fit for this car. 3:91 are a bit too low and 3:23's are a bit too high - So I will need 3:55's

Now does anyone have one they would like to get rid of?

 

I believe that Mopar made 3.73 but they were only available on track pack cars.
