Here are photos of the mounting blocks that I made, and where they are located.
You will see that in one or two places I had to use radiator-mount-style "shims" to level-up the body on the frame. My original mounts also used that style of metal and rubber/fabric shims.

I'll see if I can find an original block (and a spare "reproduction" block) in my garage, but I doubt that I will be able to find them.
