I just bought some 4:10 gears and an intallation kit for my 2004 Cobra. I was thinking of doing the install myself at the Hobby Shop on base, but after reading a few forums, I'm thinking I might just pay to get them installed. Anybody know anywhere that I can get this done/how much it might cost. Or should I just go ahead and do it myself? I've done an axle swap on my old 96 GT but this is a bit of a different animal and I'm not sure if I should do it or not. Any suggestions??  -Mitch
