Yep, she's a 1961 Belair Sport Coupe originally a 348 three-on-the-tree car from Tuscumbia, MO. Bought it off the original owners who raced it (and blew the 348 up). Came with a bent frame and all the glass, just in little teeny pieces.
They are rarer than the Impala Sport Coupes from 1961. Don't have the exact number on hand, but it was something less than 10,000 Belair bubbletops while the Impalas were more numerous at over 100,000. I'm guessing most were 6 cylinder or 283 powered cars. Not mine!
Still have it, just keeps getting shafted in terms of being prioritized...
