Attached photos of a rad support from a 53 Chevy 1 ton on my farm
It has the same plate

I think I was mistaking the locking nuts under the front on the engine mount location in my last post

It seems that The rad support doesn’t use nuts because the special riveted shape has a threaded block inside of it and the bolts go up from under the truck
