Door courtesy-light switches

Hello all.  I'm putting my rescued C4 back together slowly but surely.  Both of my door courtesy-lights have defective switches(the small one under the lens that is 'pushed' to turn the light on or off.  Does anyone know of a source of replacements?

I also need the passenger-door hatch-back release switch:

I ALSO need two "door lock/unlock" switches, and two "window up/down" switches. 

Lastly(for the electrical) I want to replace the fancy-schmancy "USB AM/FM CD" radio with a stock '85 Corvette radio.  Does anyone have one laying around for sale?

Thanks!
