Its possible Im wrong, I havent checked any part numbers or anything for the gtp, but I think you have a great shot at it being a simple solution. Do some part number research on the ofna website.
And if you are looking for a simple 2 speed solution check out Mikes 2 speed pinion adapter. He now has a whole range of pnion gears available for it. I got a setup from him and it is solid and really simple setup. It should work for your application perfectly. I was also thinking about playing around and seeing if Mike could make me som "special" pinion gears for the 2 speed adapter of his. I was thinking I wanted to get a 32/37 pinion setup to use with the Ofna 44/49 2 speed spur gears on the 2 speed tranny. I was going to target 100+ as a goof around setup on the DM1 just to see if I could do it.
I'm sure he could make (or get made) any tooth count we need. It might cost a few $ to get it, but If we both want a set we could split the setup costs assiciated with any special gears.

I think you are right...if I were to build an Ultra GTP, I'd try the Jammin CR mount and ditch the 2-speed for a center diff....I guess for the high speed stuff this is not optimal, but it is simpler and would be fun to build/drive.
