I agree I would move on. My thoughts are if you feel like your getting hosed you probably are. I had similar horror stories with people who worked exclusively on classic mustangs. I took mine in for a major tune up, pertronix install, rebuilding of the carb, and power steering, changing of all the gaskets as well. It was fine till I got it home and a week later started leaking where they replaced everything. I took it back to have them redo the work they did. The also said it was leaking around the crankshaft so i had them change that too. when I took it back I also foolishly asked them to check out the
tranny since it was revving high before shifting (my initial thought was a vacuum hose leak). They said it was internal components (i forget the details) and wanted to charge me 300 bucks just to take it apart. I finally listened to myself and told them no thanks. Took it to AAMCO, sure enough a broken vacuum line (actually cut off vacuum hose). cost me 60 bucks to fix as opposed to their 300 to do work that was unrelated. My initial feeling was right not to trust them, they were breaking things or making them worse to charge me for extra work. These "experts" would have to blind to not see a severed vacuum hose...i think we know what was really up with that. I simply don't get if they had a good rapport with me I would take it back for work and parts and spread the good word. A good, trust worthy mechanic that knows how to work with these cars is gold, hold onto that or just do what im doing now, and start to do the work yourself it's cheaper, its more rewarding and you know that you did it right.
