So far as we could find mine is the only L36 M20 2+2 convertible. There could be other models (non-2+2) as well.
That's based in part on a 1970s GM letter that I think was addressed to you!
Only hard part I'm missing is one emblem, hard to find "like new". But I've got most of the important stuff!
Did you drive that car before it was parked on the farm?
I'm wondering if you (or someone else) swapped in a Hurst shifter. I'm thinking the stock shifter ball should be silver?
