Re: Rear Ratio

the catalog of Camaro ID Numbers 1967-1993 lists 2.73,3.08,3.42,3.73,and 4.10 but does not differentiate which ones for auto or which ones for 3/4 speed.

Re: Rear Ratio

OP

you can rotate the rear wheel one revolution and count how many times the drive shaft turns.

for example if one tire rotation and DS turns 4 times....4:10's

DS turns about 3 3/4 turns..3:73, etc
