With a T5 trans i would guess you may want a rear end gear ratio around 3.5 Or 3.7? To 1 depending on your intended driving and terrain. You may just want to use a 9" rear from a 68 to 72 f100 with the gearing to suit your needs?

Many of these rearends had 3.92 rear gears. Best way to tell is hold one axle still while turning the other axle and count the number of revolutions the pinion turns on one complete revolution of the wheel. Not very scientific but it’ll get you close. If you want to know for sure remove the rear plate and look on the ring gear’s side. It will be stamped into the ring gear.

hopefully the WC T5 will be good?
