Rebuilding a M50D-HD

[lowspeedpursuit]

Seems fine? -16A is supposed to be the 4.0 input shaft for all years '90-'11. I just looked at a random picture of an input shaft I have, and it's got the ridges between the dog teeth.

You have the M5OD-R1HD. M5OD-HD is an abbreviation, same as condensing the old one down to M5R1. They're both in the R1 family.
Did you get synchros? If not, it doesn't matter. If you did, the old synchro kit is -AWS. The HD kit is -BWS.

Thanks for the clarification.

I didn't get synchros be cause I was told mine are fine by the business I got my parts from. They were super knowledgeable and awesome.
After some exchage of specs and details. They told me, because of the fiber looking material on inside, I had special heavy duty synchros and they're pretty pricey and only available through Ford. But mine looked perfectly fine so they said I dont need them.
