Can anyone identify this spring hanger?

Pulled these front spring mounts/hangers off a 73 RR for spares on my 71. Didnt realize till they were getting thrown in the blasting cabinet one was an oddball. I lined them up and the oddball is all the way to the right. Anybody gota clue as to what it is from? Too much pits to read a part # if it came from. Ideas?

Kinda reminds me of the Mopar Performance ones.But they had 2 mounting holes for the spring eye for a choice of ride height/pinion angle.

Grabber, the one on the left is from a 63 or 64 b, the one on the right is more than likely from a 65 or later, 1/2 inch difference in the spring length from the eye to center on the 63-64. my 64 is a twenty inch and the 65's were 20.5. Dave.
