Alright, finally got back out to the shop. I found that my stops are indeed bent. I pulled another set from a 46 parts truck but as the parts book says, the earlier ones have a different part number. The 1946 set of stops from a parts truck that I have are good (not bent). This is the only other set of stops that I have.They are still contacting the backing plate (barely, in one corner as shown by the scratch in the second photo). I guess I will file that corner off and move forward. Thank you to everyone for the feedback and links. Mine is actually 0.700" thick instead of 0.7500" thick and it's still rubbing.
