Question. What Engine Mount Brackets Do I Have?

[hemi71x]

Found these engine mount brackets buried deep on one of the storage shelves, out in the garage.

Haven't got a clue to what year(s) they may fit, bit i am assuming they are small block mounts.

And i don't know if there's any difference between the A, B, C, E, body cars.

Anyone care to look at these pictures, and tell me what they are for.

Thank's a lot.

Look like 66-72 SB mount brackets to me.
