Don't get me wrong. i'm not saying to go back to the original color. You do what you want. it is your car. i just like to see how cars came from the factory to educate myself. i learned something from your car, that i never knew.
Mine started out as a flat hood 318, four wheel drum,power steering car. When i bought it, it had a 440, and the performance hood & dual eshaust valence. i wasn't complaining. i added the hockey stick stripes, and rear go wing spoiler, front disc, and rallye dash.
If you want to clone it into a 'cuda, you don't need my permission. I am more than happy that you have a cool e-body!! i just personally like GC's, so i kept mine with all the badging, trim, & argent tail panel. and in some ways, it was kinda fun tracking down those items that had been lost/removed along the way.
We all here at C-C.com would love to see you restore it to your dreams!
