Thanks BrickYard. I had bought the car a couple of generations from the original owner and a lot of parts have been lost or missing. I'll have to check on prices for a custom made tank and/or just go with a premade fuel cell and put it in the trunk.
I got prices on glass from the local auto glass shop for the fron/back and side windows. What I didn't decide on was the mechanism for the side windows. It looks like the power window unit from SpecialtyPowerWindows is what I need. I've seen some from SpeedwayMotors and SummitRacing websites that might be a little cheaper. Not sure if the quality is cheaper too. I have a little time before I need them but I'll investigate.
Bought a lot of parts over the weekend from online vendors. Prices will be probably be increasing after the first of the year and some have low cost shipping right now.
