They paid me to do mine... like a Grand just because it was Notchbck93...WTF
I've never seen such a more rediculous response string of what people paid for a service.
Obviously, if you know someone or live out in Oklahoma where the ave person makes 14G a year, the cost to have gears installed will be less than someone who maybe outside a major thriving city.
I have installed all of my own gears on about 6 Stangs thus far and only one required shims to be ordered after checking lash, drive and coast patterns.
A simply, "shop around" post would have sufficed.
Sometimes you can find techs who do side jobs, but beware, just because they are Ford techs doesn't mean they are on the ball. Find a few guys that have already have had gears installed in your area, see how the work has held up, then make an educated decision.
