If it's by chance a '68 Road Runner, white with red/burgundy interior, 383/727, that's one of my old cars.
Haven't seen it in many years but remember it well.
Did the body, paint, drivetrain & etc on it, was a rust-free SoCal car.
It's somewhere in that area last I heard.
I'm in the PNW now, or I'd be glad to help.
