Casey, I never knew the hood treatment was avail. in white. That would be neat. My 72 has the white side/tail stripes, white vtop and int., with a black hood treatment. And it is B3.
I have seen two black cars and one super yellow (I think) car with the white stripe scheme. The two black cars were from late '71. All three being "original paint / options" '72 cars.
The stripe was only on the A59 package for the '71 model year - all were black that I know of.
One of the black '72 models with white hood treatment can be found on this site. Link below.
