motor mount stool question

[rauto13]

I am not sure what to call them, but I am wondering which are the correct motor mount brackets (stools) for my 72 Cheyenne, 350 engone, ps, pb, & air. Obviously this is the metal mount that bolts to the frame & front crossmemeber and that the engine bolts to. I think the mounts in my truck are for a 1973 and later truck. I have been told that there was only one set of mounts, pictured in the garage, and I have also been told there are two different mounts, the ones in my truck and the ones in the garage.

Are there two sets of motor mount brackets or only one?

I believe the mounts shown in the photo in the garage being painted are the correct factory mounts, am I correct?

Thanks for the help.
