Hey all,
I got a question regarding my rearend. Should I get my 8" rebuilt or go with a 9" which I can get for around $1200 complete with gears and diff.?

With a T-5 I'd go with 3.70-3.89.------------------

Go here it'll help  http://www.ring-pinion.com/content/calculators/RPM.asp It really all depends on what RPM you want, or willing to run at.
With the C-4 3.55 would work better on the highway. ------------------

thanks for the link. i guess if i went with 3.70's my rpms would be around 3400 with my C4 on the freeway. it shouldn't be that bad since i dont take long trips on the freeway.
