If you want to go period correct with a TR8, NOS vintage pioneer AM/FM Cassettes come up on E-bay from time to time, they are will built and I have one in my TR250, not period correct for my car, but looks better than a new electronically tuned thingy, and I didn't have to cut the dash support. If you still have old cassettes it works pretty good, if you want to listen to digital music they make amps just for that purpose that go under the seat with a remote control unit, if that is the route you go you could just put a dead period radio in the dash for appearance sake.
