Since my A-466 cast iron pig torqueflite swap will require new/shorter drive shaft, I am looking for one from a 56 Dodge (or Chrysler??) that I could modify. I wouldn't need the whole thing, probably just one foot from the front and one foot from the rear. (I would get a local drive shaft shop to make the shorter drive shaft from those bits).

My 56 Dodge D500 drive shaft is (I think), the same as one from a 4 bbl 56 Dodge 315 poly car, i.e. 4.0" ball and trunion front bit and "regular" Hotchiss cross U-joint at the rear (not another ball and trunion). If I had those bits to play with I could create a new shorter driveshaft that would look period factory, rather than having a more modern (and not age appropriate)front Hotchiss and sliding spline type drive shaft.

I tried John F. at Big M and he thought he had what I am looking for, but, it turns out that he does not.

The front Ball and Trunion U-joint has, I think, a 1635 099 housing that has a 4" flange. As far as I can tell the 1635 099 housing was used on the 56 Fury, the 56 Custom Royals with the 315 engine, the 56 Desoto Firedome and the 56 Chrysler Windsor.

This is what I need:

Now would be a good time to consider converting away from the ball & trunion. If you want to convert to a slip-yolk type, you can purchase all the parts new. The rear yolk you can purchase new too, but it is cheaper used. The slip yolk parts can be found used from many '57-'65 Dodge trucks.

I know but the "narrative" that I am trying to follow is "If Mopar installed a torqueflite in a 56 Dodge D500 car late in the 56 model year run, they would have used a ball and trunion front U-joint/cross rear U-joint driveshaft".

At least that is the story that I made up as a guide for this project.

All that said, the rear U-joint is going to get changed to a more modern one without the "ears".

Thank you George. Picked it up yesterday (I was away between May 10 and June 3) and it looks like it will work. Ball and trunion flange is the necessary (for me) 4" and it fits onto the torqueflite tail piece/drum flange bolts just fine.

Strange that the diameter of the driveshaft is 3.5". Mine is 3.25"

.
Finally got to the "new" drive shaft that I got from George a few weeks ago. I cleaned it up and painted the 3.5" diameter tube (my existing 56 Dodge V8 driveshaft was 3.25" diameter - don't ask me why there was a size change). When that was done, I took the drive shaft and the new 4" housing that I had bought probably last year and various other bits (bearings, boots, etc) to a driveshaft shop to have the ball and trunion rebuilt and the OE earred rear U-joint removed and replaced with a "7260" style Spicer 5-789X sealed U-joint to go with my 10 spline 58 Dodge-style rear diff yoke. That was done a few weeks ago but I never got around to installing it. Did that this afternoon.

When I got the OE driveshaft off, I compared it to the "new"/rebuilt driveshaft. The new one seemed to be about 1/2" shorter but I assured myself that it would be find (it was).

Note to self (and others): The nuts on the studs holding the front (ball and trunion) end of the driveshaft to the eBrake drum are 9/16" hex. Threads are probably 7/16" x 20 UNF. Heads on the bolts for the straps that hold the rear U-joint into the 58-style pinion flange are very small, 3/8". Not very confidence inspiring.

Anyway, it went it nicely and when I took the car for a drive, I think it improved things, i.e. less clanging into gear and nothing during light upshifts of the Powerflite. It will be this driveshaft that gets shortened during the A-466 cast-iron TF install (once I get the front pump issue sorted)
