77 gearing?
i have a 77 f150 4x4 frame. the truck originally had a 351M, c6, np205. the tags rusted off the axles a long time ago, so i cant tell what gearing it has. i want to know what gearing this truck would most likely have on it, and what gearing was available.
idk why, but i wasnt able to pull up squat on google

It will either be a 3.50 or 4.10, most came with the 3.50 unless you got lucky with the 4.10. You can jack up one tire and put a mark on it. Then put a mark on the yoke. Spin the tire and count how many times the yoke spins in one tire rotation.
