Hey thanks everybody for checking out here's some answers:
zman, the dashcap is from YearOne. Check it out here:
http://www.yearone.com/serverfiles/fbshopmain2.asp?cat=4jphillips3333, yeah, the wheel's from an '82. Dunno why, but considering the butt-in-the-air stance, the Appliance mags, and the window louvers, I think it was "retro" when it was first installed (probably the mid-eighties). I'm planning on finding a formula wheel to go with. The shock aren't the reason the rear's so high; it's got those helper bars on the leaf springs.
BusDriver, my friend graduated with a welding certificate, so maybe he can help me out. I don't know how to weld and always assumed it was really difficult, but I'll look into doing here.
