Upgrade for '70 Swinger 340 rear

Lowering blocks can be safely used. My ‘79 Magnum below has the 3800lbs SS springs in the back here right after install. Stink bug look for sure. A 2 inch lowering block made it look stock as a rock. I’ll do a 1-1/2 block later.

Is the Duster below more of what you’re looking for? It sits on 555 Nito’s and *I Think* (but pretty sure) there 28”. I’ll check it out later. The car isn’t near me. About a 40 minute drive.
I check what springs I have in there.
