What engine swap are these brackets for?

What engine swap are the brackets in the left of the picture for? I ordered a second set of mounts from a private seller ebay that were supposedly for 62-72 mopar b body/e body hemi swap. When they arrived, I compared them to the first set I bought straight from Holley and they are not at all the same. I know there are mopar big block mounts attached to them but I'm curious what they adapt to?

Looks like LS chevy to BB on the top left./ Not really sure though. You can have a look through the headman engine mount list. Hedman Performance Group
