Yes rear bezel for reflector needs to be painted Black as stripe color. They would "X" cut the stripe and fold it in.
The regulator in 69 if very early would have red print on it. (mostly 68's used the red print) 69 used a yellow print.

They are the good places an OE type resto would need.
Also Mega is a great place for parts too.
