ShnakeCSC,
XXLBlock is correct. Only the '82CE had the pop-up glass "Factory" installed. However.... I have an '81 that had the '82CE window installed after it was delivered. This occured within weeks of the '82 model hitting the streets. GM did not manufacture this option. It was a Cars & Concepts kit that was sold to GM for inclusion in the CE's. To date, I have the only known '78-'82 (non Collector Edition) Vette that has this window. To see a picture, please check out the L81VetteRegistry.com website, pg 3 pictures under "Nutmeg". It's a great option and I never have understood why GM did not offer this option prior to '82CE's.
Welcome to the Corvette Action Center and enjoy!
Regards...... Nut
