In the 1968 factory AIM on the RPO Options Index sheet (A1) it shows a note about RPO D88 being removed on 2 28 1968. RPO D88 was apparently Z-28 striping. This raises the question-was it possible to order optional striping on other Camaros?
D88 was the multi-color (rainbow) striping (see below, and in the 1968 AIM under UPC D88, Sheet A1), but we don't know if it was available on the Z28 because there's not enough data to make that determination. And yes, there were other striping options available on other cars. More info
HERE.
For the longest time we didn't know if this option EVER made it out the door. Then this car showed up (the one below). HOWEVER, it's never been proven (with documentation) that this car originally had the D88 striping, so it may have been added at some point in its life. Until real documentation shows up, it's still up in the air!
