'71 chevelle

I'm not sure why any alarm wouldn't work well. Even if it comes w/ a siren, you don't have to hook it up (just energize the horn circuit). Then you don't have to drill through the firewall... The only other holes I make in a car for a typical alarm install are: A) Hole for the LED. (I guess this is optional, although less deterrent effect w/o it...) B) Hole for the valet switch (some people just leave these loose in the kick panel anyway...) C) Hood pin switch or trunk pin switch-- which the car might have already anyway... Disclaimer-- never worked on that car, so I have no idea what else is involved.... Me

Don't get me wrong, there are a lot of terrible hacks out there, and you're right to be cautious. But if you bought the alarm (and install) at my shop, and we did (god forfend) break anything, we'd fix it, even if that meant going to auctions and junk yards to find original parts. And we have guys who are _very_ good at fixing stuff. But, more importantly, we'd have a lot of respect for that car. Personally, I wouldn't even touch it-- too many things I don't know about. But again, we have guys who could do it justice. Ask around-- you may well find an experienced installer who's willing to give this car the time and attention it deserves. Don't expect it to be as cheap as a normal install-- it's going to take a good deal longer. Since you know the car well, try to find an installer who won't mind you helping. As for warranties-- my shop won't take back an alarm that you installed, no matter what. But we'll happily fix alarms that we installed 5 years ago (even if we don't sell the brand anymore) w/o charging a dime. Not every shop is this accomodating-- check up front and get stuff in writing. (Just to be clear-- I'm not trying to get you into my shop-- I'm using it as an example of a better-than-average, but not that untypical place. There are good installers all over the place-- sometimes where you might least expect them...) Me
