I'm 6'2" and after doing the flat-firewall thing, the passenger seatback goes flat against the firewall. Sitting in the passenger seat, I cannot touch the front firewall with my toes! I also slotted the seatback attach straps so I can change the seatback rake a little. All this makes a considerable difference in comfort when you share the driving 50% of the time! FWIW, a gilmer belt drive is not only unnecessary for the conversion, but since its thicker, it makes things worse. The most necessary extra is a wide-body A/C bracket; these had an air pump mounted above the alternator and you throw away the pump & shift the alt up, running it off the inboard sheave of the AC compressor pulley.
