Hello everyone I am new to the forums and could use some help. I have acquired a 1974 w200 that needs a little love. I was wondering if anyone could point me in the right direction to finding a 23 spline yoke for the back of the 727 transmission. Not sure what u-joint it takes to be exact. I believe the reason it broke was because one side of the transfer case bracket it missing. I guess I would also need one of those as well. (Has the divorced transfer case) TIA

Freddy, welcome to the board.
You may be able to buy a new yoke from one of the driveshaft places, but you will need to know which u joint you have.
The United States is pretty big, maybe someone close to you may have what you need, but they don't know where you live. Gene

I bought my ‘74 W200 in 2014.

One of the early things I bought, was a 1974 Dodge Factory Service Manual for Dodge Trucks. You can likely find a Hard (paper printed) copy from a Manuals Supply company (online) or (cheaper) get a downloadable version of a scanned manual.

The Service Manual explain a lot, along with specs, etc.Very helpful in making repairs. You don’t know what you don’t know without it.

My W200 is Manual Transmission with divorced transfer case.

A driveshaft repair Shop should be able to look up which Yokes and u-joints are correct for your truck (if it hasn’t been modified away from factory parts).. You should also be able to measure parts (caps, openings) you still have and look up the specs (dimensions) that would correspond to which u-joints you need.
