You missed the point, I've done over 15 cars to this point some full restos some just minor work. If I didn't love it your right I wouldn't do it but sometimes just sometimes.....MS is right. most of the time you either break or damage 2-3 other things when trying to repair the orig problem. ya gotta expect that. at our age, everything is brittle, soft or worn out. and if it's not fun, or at least tolerable, then ya shouldn't have the car. not saying YOU shouldn't have the car, just saying $h1t happens...
Every time you go to fix something on an old classic you'll find at least five other things that need fixed. Just the nature of the beast. If you realize that going in, it won't bother you too much.
