Interesting take on things from uncle tony

yup 8 3/4 is over kill on a slant six, a rebuilt 7.25 can handle up to 200hp and you can get any gear ratio from 3.23-4.10 online same gears as the early dakota rearends.
I never knew Dakotas came with 7.25 rears, I thought 8.25 was about the smallest and most common in those.
