A-bodies with Sunroofs

I know of two '73 Dusters (both 318 cars) with the subroof in my area, and I recall a '73 340 4sp with one years ago but it was sold in the 80s. No clue where it went or if it's around. I bought a rear frame section and cut it off a '73 340 Duster in RI a few years ago. That was a race car and there was not much left of it but he had cut off the roof and sunroof parts... Watch out for the drain tubes if you cut the roof off !
