all I needed was a 1mm washer on each side and it tightened right up. I only have the back done because I accidently only ordered 2 shafts instead of 4 and then by the time I got the other 2 shafts I lost one of the hubs [] lol.
So now I am waiting for more hubs to get here. Plus, I sent DR. honda my front diff and diff internals. I do have a spare plastic diff case so I was able to put it together and I took the buggy shafts apart and used the wheel end (not the shaft) and put them in the stock hubs up front So I could put the romulins on and run it 2WD.

Works great and looks so much cooler with maxx sized wheels. I just put some bowties on for now as the komodos are expensive[X(]

Only one other thing I noticed, I didn't really want to grind those drive cups down more than i had to so I ground about 2 mm off the Upper arm where there was contact. Oh an do you have any issues with the rear turnbuckles hitting the exhaust? Mine rubs when the suspension travels about half way down. I have a slighlty longer set of lunsford titanium turnbuckles (boy are the 4 mm ones expensive) for the back and front on the way, so hopefully they are a tiny bit skinnier in the middle and will resolve this problem.

I gotta say how much I appreciate you doing all the work and research to figure this mod out. *gives rolland a standing ovation*
I really was tired of breaking cen shafts!
YOU DA MAN!!
