Chainstay Misalignment!!

Right when I thought I was finished cleaning and rehabbing a mucked-up 1982 Univega Viva Sport 12 spd, I noticed that the brakes didn't align with the wheel. The wheel was centered between the chainstays at the BB, but it was about 4-5 mm off center at the brake mount.

When I was servicing the pedals, it was clear that the bike had been through a couple of nasty spills. The derailleur hanger was torqued in some weird way as well, but I was able to get that nicely aligned to the chainring, or so I thought.

Chain replacement and brakepad replacement were the last two things I did. The chainline is off to the point that there is significant rub on the large chainring when the smallest rear and front gears are in action. The brakes can be set off to the side and work fine, but it's clear that they are crooked.

I really don't want to strip the bike back down and cold set the chainstays back into alignment. Plus, I don't have a gauge, so eyeballing it might not give me the result I am looking for (i.e. might f*** it up worse). I don't think I have an alternative, though, besides just leaving it. The fact that it's symmetrical at the bottom, but off on the top leads me to believe that it's twisted.

I'm mostly just sounding off my frustrations here, but if anyone has advice, I'd appreciate it. I think I'm just going to do my best to twist that metal till it looks right...
