ye sounds like you need custom but what makes you think you need a longer top tube? what length stem are you using?
Ive had 4 track frames the past 12 months, all 60cm+ but with 57cm,59cm,59cm & 58.5cm top tubes. the 57cm I felt was too short ( used a 100mm stem) Im 6ft 3.
I think the only frame Ive found with a 60cm tt was some Fuji model.

for custom I'd go with local steel or this
