Harms,
I'm doing something similar, rebuild on the cheap. While not investing a lot of money, the trade off is investing more time, both in looking for parts and in doing the work myself. That said, Swap Meets, any and every one you can get to. Mopar, general, hot rod, whatever. I've found $40 vinyl tops, $20 & $40 Auto consoles, even found a $100 Manual Console at a Chevy guy's booth. eBay will sometimes yield bargains, if you're not in a hurry, I bought a flat hood from eBay and when I picked it up, the guy had a sure-grip pumpkin he sold me for $100 in nice shape. Just keep turning over rocks. I'm having as much fun finding the stuff as I am working on the car.
P.G.
