I Just bought one new from Mike... It's only $40 bucks or whatever, well worth it IMHO. I thought RCM was continueing to process orders while Mike is out?
Replaces rear center diff bulk for mounting a single electric motor at the right rear position of the truck (behind the steering servo).... Requires modification of the stock radio tray.
I believe thats a negative - I think the with servo units are alse $50+
