These cushions? Also consider new body to frame mounting and shim kits. Chev's of the 40's should have everythinig you need

 

The Filling Station is a good place to check for just about any old Chevy part as they usually show it if it exists in reproduction. That doesn't mean that they have it on the shelf but that they have a source. At least from my experience with one of my OT trucks.

Link to Chevs of the 40's page that also shows the bolts, nuts and washers in another spot. https://www.chevsofthe40s.com/shop/...&showcase=&searchtype=FT&method=KeywordSearch

Prices are the same with either place so it may depend on who has it on the shelf.
