No such thing as a heavy axle.Someone made that up.All 32 pass car and pickups are the same.33-36 will interchange as many probably were.
Leeport, where are you? I am in Kerrville. There is the EFV8 Texas Tour here this weekend. The axles that came under 32's should be called 32 axles. There are no 32 heavy axles. There are no 32 light axles. The replacement and later axles were noticably lighter. There are 32 axles and 33-36 axles and that is it.
I used to think that too seeing several of them on some Canadian '33s and I bought a NOS one at a Canadian swap meet, but then I bought a pretty unmolested '33 coupe built in Canada that did not have one and I also started to see them showing up on '33s built in the U.S., so based on a small sample, it seems less than conclusive.
