Z28's would show the "-" special paint code on the cowl tag so that Fisher wouldn't paint the trunck stripes, but all other stripes we GM's to paint and they didn't use any of the codes on Fishers tag to determine what options went on the car. Heck the front end wasn't even near the rear body tub when it was painted, it was in a separate paint booth, and was never near the body until it was installed.
If he's got an L78 with a dash paint code it has to have been be a non standard color originally, or a color paint that was discontinued earlier in the model year.
If I understand your point, Mark, you are saying the dash(s) on the TT only pertained to work performed by Fisher (cowl on back), so that front striping delete (non-Fisher work)would not show a dash on the TT. Correct?
First, I am not sure that I agree. Having said that, I am certainly no expert on any of the ordering, building, selling or any other operation involved with production of early Camaros. I do have a 69 L48 car with 2 dashes on tag where paint code is located. I wondered why this was the case as the color appears to be standard color (LeMans Blue) and, in my case, no stripes were deleted. KurtS pointed out that the dashes are probably because the D90 stripes are white, but the car has a black vinyl top, the default color shows a black top would get black stripes! Now, I am not sure were the default color change (dashes) affected the top or the stripes? I mean, was it ordered with a black top (default stripe color was black) and a requested the white stripe or was it ordered with the white stripe and a change in V. top color? The later example would point to the Fisher end of production. This would support what you say, but , in fact, is this the case?
The second point: The last sentence regarding the L78, being this is a Big Block car, couldn't the paint delete be the tail panel black(Fisher side)?
