Packard Forum Index » V-8 (1955-56)

Here is the situation: not including my 400, I have a 55 Twin Ultramatic, a second one for parts, and a 56 Hudson-style Ultramatic. I suspect the 56 will be in the best shape to rebuild and I would prefer the aluminum body.

Question is, could I replace the propeller shaft + details on a 56 Hudson Ultramatic with 55 parts, and use it in a 55 Clipper Deluxe?

Can almost guarantee yes.

Thanks. I think I’ll piece it together before buying a rebuild kit.

Speaking of which, where do people tend to get those? Looks like the choice is between Kanter and Fatsco, and Fatsco has two options.

Fatsco regular:

Fatsco bigger:

Looks like the difference between them is just the steel high clutch plates. I’ve heard that those only need to be replaced if they’re burnt up / damaged, so I think I will inspect that first.

The Kanter kit appears much the same as the Fatsco bigger kit, but is 20% cheaper. Kanter doesn’t itemize particularly well so I’m not sure if there is stuff missing in comparison.

Max Merrit has rebuild kits and parts available as well.
