Way cool - great shape, too!
That permanent compression gauge is something... I wonder where on the block he tapped into?

Personally I would go with one of those "hidden" audio systems run by remote control; that stock radio looks too much at home (and I bet it still works!)
BTW, is that an 8-track case in the back seat?

Most of all HAVE FUN in your project!
