I bought a 901 5-speed from someone on this board with A-F-M-S-X short gears and installed it into my '67 SWB. (BTW, short gears are *really* fun). Can anyone tell me if this gear set has a name, such as the term "airport gears" used in 356 circles? Could this be a standardizzed set such as "Hillclimb" ratios (901/52) or "Nurburgring" ratios (901/51)? Or just a custom build?

They sure work great at Infineon.

Thanks,
