Technical 1937 Pontiac Deluxe parts

New guy here, So my father in law recently purchased a 37 pontiac deluxe. I dont know much about these cars as im more of a ford car guy.

The car is pretty much original aside from the older 350 crate engine/transmission swap. We've been looking for replacement suspension components and i dont see much on the market for these cars. Do you guys know a place to find these type of parts? Also are there any earlier or later years that have interchangeable parts?

Thanks for any help!
Chris
