Does a HD rear spring/shackle hanger exist for a 68 Dart?

It would be an easy part for me to make but I'm trying to slow down that stuff. If I had a car I was working on then I'd probably sit down at the brake press and hammer out a few sets.

I'm helping a buddy hot rod his 63 1/2 Galaxie 500 so I've been building some custom stuff for him. We put a Calvert split mono leaf setup under that car. Not a bolt on for sure! Had to cut and weld on the frame and build custom parts. I enjoy building parts for one car at a time. Can't make any money doing it but banging out production parts gets old after 20 years!
