We just went through this, with a 69 Charger; Some metal not availabile.
Between Harbor Freight, and Northern Tool; they have some brakes/rollers for under $500. We made all kinds of parts, off the sheetmetal left over from my Duster.
Thanks for the advice and have gotten help here already. A lot has surprised me about my project so far and don't really know how to plan what needs to be done. It's kind of overwhelming see that a lot more needs to be done than originally though.
