360 Motor Mounts for B Body

Hello A Body People, I just picked up a 360 Motor that I will be putting into a 72 Duster, the motor came with pretty new set ( 1 yr only ) Motor Mounts. The guy tells me that the motor came out of a 70's Road Runner.
I have posted a few pictures of the parts. I would like $80.00 or make me an offer plus shipping ( $ 25.00 ).
If you would like to talk more about them please let me know.
There is a number on then Says 2250.....
I live in Howell Michigan.
