Merv,
I used an Alpine CDA-9886M head unit mounted in the boot and an Alpine MC20 controller which fits in a 2" guage hole and it only needs about 2" in depth if you have no room behind your dash.
It sort of matches your speedo and tacho. I painted the face on mine black.
Also fitted a 3.5mm jack between the seats for earphones.
Put a couple of three way speakers behind the seats.
Also look up tune trapper aerial.

Works a treat..
