All the parts books that I look in have this listing for the rear motor mounts:

1937-53 ALL COMM (exc. ½ ton) pn 3702198 changed from pn 595741

1947-53 ½ TON (2nd design) rear mount is shown as pn 756700. What the difference was in the ½ ton rear mount I have no idea. I’ve always been under the impression that they were the same on all of them.

I see no mention of a “HD” rear motor mount in the 1929-1950 or 1929-1954 parts books. I also looked at all the indexes of the 1947 thru 1954 Chevrolet Service News and the only mention concerning the rear mount that I could find was a reference to the 30° angle change made to the rear cross member for the 1954 model year .

There is an illustration in the early parts book of a pn 598097 mount, however it isn’t listed in the text. That mount looks like it has the same mounting holes as the pn 595741 but has a thicker cross section.

It seems like I’ve seen those cylindrical mounts before but without having an original 1947-53 ½ TON (2nd design) pn 756700 rear mount and an original 1938-53 UTILITY pn 3702173 mount in front of me, I’m really wondering if those mounts in the picture just weren’t some aftermarket motor mount sold by an auto parts outlet.
