1) Does anyone if it is OK to weld such mounts on the frame of my 1937 Buick Roadmaster?
All steel construction is designed to flex. If it didn't, it work crack and break. Just so you know for future reference a rule for welding frames is to avoid a vertical weld on the frame sides. The items you are talking about welding on should be fine.
