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.

EDIT: From post #8.
Do i have a mix matched set of mounts?
A big block mount bracket, and a small block mount bracket?
That why holes are drilled on the other side on one of the brackets?

Member Lemondana has informed me, that the mount pictured on the right is a 383-440 big block mount bracket.
That would explain why the holes are drilled on the opposite side of the one that i have, other than a small block bracket.
Thank's everyone for your input, with my inquiry.

I have come to the determination, that i have both a small block bracket, and a big block bracket.
Been decades ago, since i wound up with these parts, so i don't remember that far back, how i got them.
Probably just lying on the ground at a U-Pull-It wrecking yard, back in the dinosaur days, just waiting for me to pick them up.
Thank's everyone.

You need measurements to be specific.
Not as easy as a picture to tell other than small block or big block.

Look like 67-72 small block 273-318 to me. The passenger side with the step is not familiar to me what body style it came out of...

What "measurements" would you require of me, for you to determine what mounts these are?
Would you know?

Appears that i have a 340 bracket, but the bracket that i have pictured on the right, has the holes drilled for the rubber insulator, on the opposite side.
Would that, does that, make a difference?

I never had, owned, a small block engine.
Always 383, 440, Hemi engines, so my unfamiliarity with these mounts, had me ask these questions.
Have no idea how, where, i came across them, decades ago.
I will advertise them, for sale as 318, 340 mounts, if i can officially determine what they are.

Typically it is width of the bolt holes to bolt holes
