All 12A mounts are the same. I'm not sure of the differences, if any that lie in the 13B mounts. I do know the main engine cradle/crossmember is different for the 13B.

so it really doesnt matter if the 12a came on a rx2 or on a rx3, the motor mount in the end will be exactly the same ?

EDIT:

Check this one, according to the owner this one came from a 72 rx3 and they dont look that identical

it bolts up to the crossmember the 12as are diff from 13bs. and i would imagine that the 7s are different from the others. but rx7 12as should be all the same and 13bs should all be the same. but they are slightly different from each other

The front mound or mount that the engine mounts attach to are all the same for the 7's. Does not matter if it is a 12a or 13b.

It is the cross member that is different between the 2.
