switching from 48 to 32 pitch need help

[redshift]

A buddy has an older Stampy with this same problem... could one of you list the parts required to do the Mod1 conversion?

Again, this is for an older plastic-geared trans, he does have the aluminum idler already. Traxxas or Tower part numbers would be much appreciated.

Other than spur and pinion, I'm guessing only the newer input shaft and slipper assy. will be needed. My other concern is motor shaft length. He's got a few yr old Novak 8.5 5800 kv unit
and with the increased offset of the new slipper I'm wondering if there'll be a problem getting full mesh?
