X-Maxx Project (Long but please read)

[GorillaMaxx360]

Ok i have took away and added many things first Away with the ti arms and 3.3 stock turnbuckles. I added a single speed, gmaxx 3.3 race suspension, MIP 3.3 cvds, (man these things are thick) maxx 3.3 tubes, center dogbone, and some carbon fiber hinge pins. And still on the way are some wicked tire and rim combination on 23mm hubs. Did have one question for you guys though. the cvds/dogbones for the center of the truck won't fit. I grinded the front one to make it fit but it became to tight and it fits but it binds. The rear one was not grinded but it fits snug and binds too. I am using the flm hybrids with hb diffs and hb diff cups for pinions, and an FLM dogbone in the rear and a rc monster 72mm dogbone in the front. Do you guys have any idea on what i could do or what sizes i need thanks.

Here are the pics (sorry for poor quality)
