does anyone know if i can get a longer input shaft for my setup because those 4949rs are not gona go in the cup properly do to me having 4907 differentials...does the revo have a longer tranny shaft mine is the 4909 tranny with foc it has a 80 mm shaft i need one longer with maybe a couple extra mm on each end on it for the dog bones to go in without worrying if theyll come out.i really am trying not to get the 4909 diffs which would solve the problem but i already bought the 4907 diffs. and i really dont plan on getting some more. but if i did perhaps, can i just put the sealed stuff in it like whats in the 4907 diffs
