Thanks guys. Unfortunately, my job is 7-days/wk, so I don't have the time to go to the salvage yard (or the fabricating know-how) to go the re-purpose route. I take an auto mechanics class a couple nights a week at the local high school, so I could probably get some help there.
I found two companies going by the Electric Life name.
www.a1electriclife.com and
www.electric-life.com. Both offer kits for early a-bodies, and E-bodies, but nothing for A-bodies between '70 and '72. I'll call them to discuss my '71 Scamp and see what they say. Kits from these companies run around $250.
XV Motorsports seems to have a direct fit kit for $499. Even then, their site indicates I'd need to send them my regulators to have them work something up for my particular model year. $499 seems like a lot, but then again, how much is my time worth trying to make something that's "almost right" fit?
Since my goal is to turn this Scamp into my daily driver, power windows would really make this a much more hassle-free ride. I'll keep working on this and let you guys know what I come up with.
Thanks again for the suggestions!
