Was going to see if you could tell me something about mine. I believe it is a 3.50 gear also, but want to know the rest of the code: WDM CJ 8MC 2 75 9 356A Thanks Scott

 

WDM-CJ = Ford 9" / 3.50-1 / non Limited Slip / 28 Spline Axleshafts.

2) D8TZ4234E .. Axle Shaft / Use with 3/8" backing plate bolts.

It was, at one time, necessay to know what size these bolts were, because 1978/79 E/F100/150 & Bronco 9 inchers came with two different sizes (the other is 1/2").

In order to get the correct rear axle internal parts, one had to know this jazz.

8MC = Assembled the 3rd week (C) of December (M), 1978 (8)

 

that's interesting. I figured that it would be a lot more since it's only a 3 speed.

thanks for the formula.

 

3rd gear is 1:1

 

Thanks for all the help NumberDummy. When it comes to codes and part numbers and fords period you are them man. I put a post in the small V8 section with the numbers off my 302 motor. Can you help me there if you have time. Thanks
