The center diff for the Mammoth ST is 65 tooth and people race it with a 12-13 tooth clutch bell with no problems so I'm sure the MT2 can run it also, but like you said clearance to the chassis might be a problem.

Before you go ginding and drilling the JT chassis wait to see if the company you mentioned is willing to take you up on your offer about the towers and chassis. Or maybe even wait until you can afford a kit like the Ofna R2 and use the JT chassis for the OS engine.

I believe that Ofna has a center spur with a sliper clutch built into it. I have seen one but I'm not sure who made it.
