My high school auto shop just got a 99 SHO with 48 origanla miles on it. aperantly it cant be sold because it was in a flood in nabraska at the dealer and all this leaga sh is involved but when you just turn the key to power it pegs 55 and starts rolling the odometer lol guess the flood fd its comp up but any ways its got a mach system in it with a 6 disc changer in the back do oyu think it will work with my mach 460 stereo and how could i do it
