newbee: Need some sound advised on my 70 "H" code Duster!!!

Welcome Dibs, I think should restore it to original condition and then later build a twin the way you want it. When you are ready, i have the twin in Livingston. It's just a shell but H code 4 speed. Good luck with your car. it looks like a great car. Sometimes i find a-body parts at Canton swap meet. ever go over there?
