2 - power steering pumps

I have two power steering pumps. I am guessing they are from a early to mid 70s mopar small block. They look the same as the one of my '74 318 Duster. One has a bracket on it, the other does not. They came with my '73 340 when I bought it... Both pulley's measured in about 6 3/4" I would like $35 for the one with brackets and $30 without plus shipping. Any questions, please let me know.
Thanks
