I have installed a number of sound systems and subs in my friends, brothers, and my own car, and have done a lot of other work. I'm about to install another one infact in the next week or so. I changed my friends calipers on his TJ when he busted it, always have my Jeep apart working on it. Tons of people know that Im a car guy and so I'm always changing peoples flat tires, or they always come to me to jump their cars cause they know I have a ton of stuff (tends to happen a lot in a high school parking lot). Except for some reason I do all this work for others for free. My parents keep telling me to charge people, but I just like doing it.
My shop told me it would be about $800 for slip yoke and 2 inch blocks/spacers installed, I'm doin it myself for less than half the money.
Karl, You are one lucky bastard with that Jeep, I wish I knew some people who flipped their rides and have their parents give it to me.
