Turbo 350's are a 3 spd tranny. I doubt you'll ever hit overdrive - even with a gear swap :D :D :rolleyes:

You should be able to find used gears and a carrier for less than that. Try JKL Auto in Maple Ridge.

you should first find out the drive train you have then the gears there is a splicer site dana has . it has all the calculator's you will need to figure out.
if you have tires that require better gears you might as well get the right ones the first time rather than install some and find iout you didn't go big enough . i have a full size blazer with 38.5 boggers and i moved from 30.8 to 373 and it goes nice
