Not to hijack this, but does anyone know if you can swap red lenses into the 1960 back up lamp unit with clear lenses (part no. 988077), or are the tail and back up lamps different sizes?
Funny you ask, just what I'm doing. NOS lens off eBay, GM # on both boxes 5950694. The entire kit is GM # 988077 as James stated above. The lens screw right on.
