Plymouth duster rear suspension questions

You're better off without the circle track springs. I bought them, put about 20 miles on them and threw them in the trash. Photos of the problems are in my build thread. I went with the Hotchkis springs and never looked back. I'm using the old MP offset spring hanger which has two mounting locations. I'm actually in the process of reworking them with 3 holes to have more adjustability because I want to get the back of the car down. In comparing them to the spring hanger that came with the leaf springs, the holes are either higher or lower than the Hotchkis hanger hole location. I'm setting them up with the center hole in the same location as the Hotchkis hanger. That way I have one step up and one down. I'm not familiar with the Dr. D hangers and the relationship of the holes.
I'm running a 10" wheel and a 285 tire with a stock wheel well. I do think a 10.5 or 11" wheel would fit if the wheel lip would be completely flat, mine is just trimmed. The next problem with that is the "hump" in the outer wheel house, but that would likely only be a problem for a really low car. View attachment 1715933911 View attachment 1715933912

That's a spiffy lookin' Duster... I'm diggin' it.
This is giving me some ideas.
