All 914s 4 & 6 had the white (off-white) headlight surrounds which were solid white colored plastic through-&-through up to the 73 MY, then they switched to the black (solid black plastic through) for 74 or 75-76 MYs.
The later replacement parts would've been black after the whites were gone, & that may be why GTs are seen with black surrounds, cuz I've seen pix of them with both white & some black surrounds.
If they are painted over black from white or visa versa, then the paint may be able to be stripped off without damage to the underlying color.
PS - Assuming yours are white underneath - try stripping the black paint on yours with mineral spirit of paint thinner carefully. Once stripped if they look yellowed or darker than when new (like the pix above), then you can soak them in chlorine bleach solution - or maybe oxi-clean bleach solution - to lighten them back to original, as folks have long done with them & other white plastic parts for resto's when yellowed or browned from age. I would NOT sand blast them, but soda blast may be okay, or it may eat into the surface a bit.
thank you - trying this tomorrow.
