Yeah my question also, but just verified numbers
via photos I took of the rear end. Numbers are correct except the is an X over the casting number and an O over the date. I got the car partially started and am finding things don't match up,
thx, Howie

3.36 chevy 10 bolt is my best assumption also. Trouble now is figuring what speedo gear to use, I'm guessing a 42 or 43. ANY HELP???
26" tires, 18 tooth output shaft speedo gear?
Thx, Howie

I ended up having to call a tranny specialist. He said with 26" tires I'd need a 46 tooth gear which is not possible. He said I'd be 1.5 mph high at 50 so I will use bigger tires and that will fix that. Thx, Howie
