New E-maxx tranny

[E-Revonut]

Is it true that the new tranny won't match up with the mounting holes for the original tranny? Any thing to solve this? I just tried putting the traxxas single motor plate on an original tranny and that doesn't work either, mounting holes are WAY off. Is it possible to make a hybrid tranny? Or should I just get the goriila maxx single plate? I wanted to have the dust cover on as well for a cleaner look, a cleaner chassis, and no rocks or dirt destroying my gears. Any help is appreciated.
