Street Freaks, Customs, Rods, Street Machines...60's 70's 80's

That's what I found remnants of on my 67, white paint on the rear, springs, and even the spare tire well.
I thought the white on the spare tire well was overspray, as it had been spray bombed black after.

What is the extent of the white paint, how far does it go on the underside of the floor?
I see the shocks, backing plates, and possibly the inside of the wheels.
