Does anybody have a source for transmission ratios for a 72 C-4? Also, how do I know how many splines are in my rear end, besides counting them after disassembly?
Thanks

1967 F100/350's with the 352 V8 used MX Cruise-O-Matics.
1968/72 F100/350's with either a 360 or 390 used C6's.

Rear Axle: 1969/72 F100's with a 302 used 28 splined axle shafts without Limited Slip, 31 splined axles with Limited Slip.
Not sure which axle you have?
Look for the AXLE code on the VIN plate.
Post the code here. The FTE axle decoder will not decode 1972 and earlier rear ends codes.
