If it doesn't sell I'll be doing the same thing to my m51

I helped patrick build that truck. Most of what I helped with was putting the 109 box on the chassis, but he didn't mention any troubles putting the t case in.

Final drive ratio is different.

Edit; the link above gives the info.

Truck should go faster since the 939's were an overdriven case in high range.

Yes, he says it does. Too bad there is not a similar change for the deuce.
