'70 Duster build-up...

Awesome looking Duster! :thumbup:

What size tubing did you make the frame connectors out of?

Oh, and I'd bet that's actually an A body 8 3/4. If it were a B body, you could run more than 4.5" backspace without getting into the springs. The wider rear and same location for the perches means you can run a lot more backspace. Pretty helpful actually if you're running larger, newer rims (like Mustang Bullits) as they all seem to have a ton of backspace.
