Well, for '71 you'd be looking at roughly 1255 GT's. That's a % of a production number though, not an exact documented figure.
But I don't think those were the only bucket seat/console cars that year. I'm a bad person to ask though since both of my '71's are GT's, so they're both set up that way.
Would be interesting to see the fender tag for sure. Or the buildsheet, depending on where it was built. Looks like the upholstery is all intact, so you might have an intact buildsheet too.
