It should fit, they are not as big as a plett, and the plett motor had a slight interference fit with the lower plate. I ran 32p jato spurs (58t?) and a 15t pinion and it meshed up fine with the plett.
Now you may have issues with the diff internals holding up, but that is another story...
thats all upgraded already, i was running a 6l but my buddy wanted it and I have this 8xl just sitting here, i figure it should turn a big pinion so that should be fun
