Help with installing a period correct radio with Bluetooth

[JimmyCamino]

Jamie - I installed the same radio (USA-740?) in my '84 El Camino. It was as easy as any radio installation. Nothing trick about it. You can do it. - Jim

I always notch the rear deck to fit a 6 x 9 directly without adapters so they clear the trunk bars and I also cut the opening to match the 6 x 9 but I am also not concerned with keeping something stock.
