If you have the car and you have the hurst roof, then you already have everything?? Since these were cut into hardtops as required, I'd be tempted to go that way rather than chop off an entire roof for the same result. Use it as a template after making sure t-tops and seals fit properly, and transfer it to your own, but do it neatly and not rushed like under factory conditions. The Fisher roof is the swap candidate, perhaps change that to has anyone cut Hurst tops into their car or done the swap? Only a thought, I don't have experience with any t-tops.
