dino.tw ... Not true... You don't have to change the chassis to do that conversion. True you will not be able to use the 5th body post, but after looking at my 2 G4's and the pics, the conversion is very simple. Much like the Mugen steering system. I have the MTX 3 as well... Everything in those pics are stock except the steering system... On the stock chassis there is a pass through hole at the same point as the 5th body post at the top... The conversion would be very simply to construct and install... Just waiting on TM or who ever... Also, in those pics you posted, I notice molded plastics in the conversion... That guy just didn't slap that thing together... Someone manufactured those pieces... I also notice the link came from TM's web-site... Thanks for your help and if you find anything else out... Please post... :-)
