For what it's worth, I would have told you save your $50 and use it to buy a repair manual and do the job yourself. Mainly because I can't stand paying someone to do something I know I can do myself. Besides, that $50-60 quote probably would have turned into $80-90+ real quick. So I say good kudos to you for doing the right thing and keeping your money.
Yours truly, sincerelly, love always, Josh aka The DirtDemon.
