Correction . . . My bad. 2,536 1960 Thunderbirds were equipped w/sunroofs. Of those, 377 had the J-Code 430 "BIG Block". Of those eq w/leather, AC, pwr/wdo's etc is unknown.
At our 2006 VTCA concours, there was a club member there who had moved to Nevada. He had the orig build sheet (retrieved from rear seat area). It had the 430, factory installed AC, and . . . AND black seats w/gray cloth inserts. It had every power option Ford offered in 1960. There were a few oddball things on there. It had a pwr brake unit I had never seen before. It was one cherry ride. You may recall seeing it on the Sq/Birds calendar (cover) a few yrs back. The gunmetal gray one. I think Alexander really liked it (putting it on the cover and inside)
