Starting a 72 duster project

Hello everyone I'm new here and I'm gonna need all the help I can get. I've got a 1972 plymouth duster thats a project car. The body is very straight and id say there will be very little body work. The interior on the other hand is gonna need attention. My question is if there's some kind of manual on these cars for the inside. Steering column,wiring and that sort of stuff. Some stuff I have but I believe I'm gonna be missing some parts and bolts. If anyone can think of anything it would be very appreciated
