Thanks Ghostrider,
Your setup is the same as mine. Solid front cab mount with shackle mount in the back of the cab, but it stands to reason as my handle attests, my truck is a '52 Chevy, same as yours.
As far as I've been able to decipher, there are 3 (or more) types of cab mounts. 1947 = Single radiator mount + solid front cab mount + single rear cab mount in center of cab. Later models fall in 2 or more categories: Single or double radiator mounts with shackle rear cab attachments and single or double radiator mounts with solid rear cab attachment (similar to front of cab attachment points).
If anyone can put years/models to these different cab attachment configurations, I'd be really appreciate it.
Thanks all.
52 Chebby
