I don't think the stripe actually existed. This specific car is supposed to be one of 100 that was built on the GM show car account and is a late 68 car built somewhere around the end of April 68. For what purpose I don't know, it was delivered to NY and now resides in CA. It is an L34/M40 car with alledgedly 30 options on it including C06, C07, C60, D55, D80, J50/52, L34, M40, N33, N34, N40, U17, U46, U57, U79, V31, V32, Z22, Z27, Z87, ZJ7, probably power windows, and tinted glass as well as a few more minor options. Story is that it was one of 100 cars built this way and is one of 4 remaining. We all know how these numbers are arrived at, but that's the story. Supposedly the car also contains numerous 1969 pieces even though the car is 100 percent original with only something like 10K miles on it. This batch of cars if the others still exist are most likely the only ones out there with the D88 option.
