Thanks Steve,
Hunting for original rear mounts is a tough one. I've been given a couple of leads fortunately. If those prove to be a "no go" I'll have to figure out something else. I really don't have much to go by as the original mounts are gone and have one bracket that is intact. There are pictures in the forums of original mounts. That has been helpful too. Unfortunately I can't use the picture to solve my issue. 😩
I may have to improvise mounts using the new style round mounts to keep it sorta original. My other option is to investigate using the newer type mounts.
I was hoping someone who faced this issue had some suggestions as to what they tried/used/did.
