giga crusher conversion

[jollyjumper]

i was thinkin of doing a giga crusher conversion to brushless.
i'm gonna ditch the center tranny and 3 speed al together.
i was sure on the fact to use twin force parts for the center.
i was gonna make a chassis to mount those parts on.
but seeing no pinions with 5 mm bore and 32 pitch, i have questions again.
do 5mm bore 32 pitch pinions excist?
or should i ditch the twin force parts and use a center diff so i can use mod 1 pinions?
