73 Duster - Need Help

SGGDuster said
I have HD springs on there and I would imagine a 255 would easily fit. I don't know about the 275 though, maybe with S/S springs you'd clear it.

Stock slant six springs/shocks it barely clears my duster..however, i am running 3 3/4" backspacing on these rims, a easy 'nother 1/4 inch will clear the spring and the lip im sure.
