I have a 96 contour that has the 2nd DIN pocket but have never been able to figure out how to remove it, that might concern you.

I can't help you much on the mach 460 but I can say if you want a stock looking stereo Nakamichi falls in there pretty well. You could get a TD-45z specs and a music bank changer like the MB-70

that's all I can add, if you are set on the mach 460, good luck!
