Hey guys, does anyone have a user manual or exploded diagram of for the Rampage XT v1? Basically I'm trying to upgrade the differential mount to the alloy one, redcat part number 71007. I'm not sure which version the xt I have and trying to figure out if a v1/v2's differential mount set, bearings and clutchbell can be upgraded to the latest version, not sure which version it is on now. how many are there now, v3 or v4??? With the user manual that way i can compare the chassis part number between them etc.
