'69 DartTrunk Mount Battery Disconnect Switch

OK. So I want to mount my battery in the trunk of my '69 Dart street runner and need an exterior disconnect switch to be NHRA legal when racing. I don't want to cut through the visible exterior of the body. Anybody got any creative ideas to solve this dilemma? 20 years ago I mounted the switch through the lower half of the rt side tail light, but don't really want to do that again. Help!
