Hey there
We have a early 80's (83 I think). Can anyone point me to a website that will decode the rear end cod. I have tried to search but my e-net connection is so poor out here that I give up. The code is WCX R 3 H O 230875S279D (THE WC MIGHT BE A WG). we rotaded the wheel 10 times and counted the u-joint revolutions devided by 10 and come up with a 2.85 but seems rather low, anyway any help would be appreciated

there is a 2.73, 3.08, 3.27, 3.45 and 3.73. 4.10, 4.56 and 5.13 for a 7.5 I do not know the others size of rear ends though. Good luck Bobby

pull the cover off the reaerend. rotate the gears until you see 2 numbers stamped on it.
devide the big one by the small one and there you have it. EX. 37/12 = 3.08
