Building a G3R need some help!

Hi Neil! Hope all is well in Limeyland! Did you get burried in all that snow? :P

So, could I take the 3905/e-revo and use the G1 conversion kit on it? Or, do I have to use the 3906? I am also assuming that the bolt pattern is different on the new transmission right? I did see a post showing someone who did manage to mount an E-Revo transmission but had to drill and tap new holes........ Just don't want to screw up and order the wrong parts!

I like the G1 Conversion cause it frees up space on the G3R and I'm thinking that may be a good place to mount the MMM.
