Make a list of pieces needed that are NOT in production. Haunt the swap meets as well as the established Mopar websites that have Classified or Parts For Sale areas for those items NOT being reproduced or remanufactured. Even ebay. First have a feel for what these items are selling for in the condition you want, then when found - pounce on it as long as it fits within your budget.
Make a list of pieces needed that ARE in production. Anything that can be bought new such as sheetmetal, weatherstripping, wiring harnesses, gas tanks and such should be. Our cars are approaching forty years old and more and time waits for no Mopar so go new - as long as it fits within your budget.
Have an idea which individual(s) or company(s) will handle which particular task - paint and body, engine, trans, rebuilding the suspension, etc. Write these resources down along with what you'll be asking to be done. Have patience and move forward - as long as it fits within your budget.
Anyways here's my plan for a shiny, better than new, Mopar:
1. gather the parts and have patience grasshopper
2. disasseble - lots of pics and baggies and patience
3. paint and body - and lots of patience
4. suspension, brakes, fuel system
5. electrical
6. interior (and vinyl top)
7. exterior
Of course scale things back if you're going for a driver as opposed to OE Gold at the Nats
