so i have a '57 ranchero 312 v8, and i just put a t-10 trans into it. changed the front Ujoint, i have a 9'' rear end, need to get the gear ratio for you. so getting into first it gives a nice shake, i can hear my bed jumping. so i lifted the rear end and put it through every gear with no shake. i dont know what it is. so to get into 1st i almost have to dump the clutch. any suggestions. i used to have a 3sp with oversdrive in it.
