54543 Aluminum Cup Joints for TB-04 Gear Differential Unit (Long & Short)
I'm using those TRF417 alu diff outdrives in my TA06 gear diff.
I do use 2 sets for just 1 gear diff, cause i can only use the short ones of that set.
Perhaps it's also the same case for a TB-04 gear diff. try to do some measuring about the sizes of the long and short outdrives and let this checked by other guys who have those TRF417 alu gear diff outdrives.
