As I am sure everyone is aware, our 1990 ZR1 Corvette first retail customers were mailed a box we refer to as the Pizza Box. I received mine about ten days to two weeks after purchase from Capitol Chevrolet in Nashville in 1990.
If memory serves (I am 64, so...) a copy of the window sticker with perforated sides and peel and stick top and bottom was included in this box. When I purchased my current ZR1, this extra window sticker was included and intact. Unfortunately, the original window sticker had been removed by the original owner and the attaching portion was discarded. I ended up scavenging my extra sticker to re-attach the original. Since then, I have been on the lookout for an original extra that I could swap mine into.
After finding one from a fellow member, here at ZR1.net, an acceptable price was agreed to and a deal was made. I received the sticker yesterday and, this morning, I carefully made the swap. Now, the original is on the window and the extra is back to its original configuration.
