Thanks for your replies and links. It's great information that is much appreciated.
Another question has now sprung to mind regarding blackouts.
My car is a factory SS/RS 350 (4P) now cloned by a previous owner into a SS/RS 396, quite well done I think, and probably worth keeping as a BB car as I don't have the original 350.
After reading the CRG information, I have worked out the sill panels were not blacked out on the Tahoe Turquoise (Z 22) cars.
I am however, unsure whether the tail panel on BB Tahoe Turquoise cars got the blackout treatment.
Any advice on whether to blackout the tail panel or not?
Joe.
