Building a 70 charger from scratch. I have a few ?'s

[JB400]

Sounds like an interesting project.  I have a relative doing something similar with a Dodge pickup. He's putting a late 70's cab on an old asphalt late model.  Unfortunately, he's wanting to use a Chevy engine

I think I'd use like 3/8 rod bent along the contours of the roof to support the roof, then weld tabs on it to match tabs welded to your chassis.  If you haven't done it already, I think I'd also mount your doors and  side panels on first, then mount your roof last.

I like the idea of the 3/8 rod. I think that might work good. Sounds like a cool project on the truck. Is there a thread on here?

Nope, he's not into online chatting.  I'm sure others have done similar projects though worldwide.  His project is still in pieces.
