Eric,
I was lucky enough to have ordered and sold them when new. They were so late in production that reproduction will be VERY hard, since the 1972 VIN included some pertinent information, including engine, etc.
I sold one or two myself and my sales guys sold the rest (big metro Atlanta dealer then). We had four or five, I believe, of the original 286. The local Atlanta zone office was pushing the "Corvette" dealers (those that weren't scared by them and sold quite a few) to order them. They knew the LT-1 wouldn't be available for 1973 and had plenty of low compression LT-1 engines to use up in Corvettes and Z-28's. (Had a few of those too!)
Yours is beautiful! We had an Elkhart Green/Saddle leather coupe and a White/Saddle leather (full optioned) Convert with hardtop that were among my favorites.
