The rear axil mod and put up front was one of Mike H. early mods.  I remember seeing it a Zooki Melt.

It did fit with little to no room left.

He used the complete rear gearing also.  Figuring even running the larger rear gear backwards (rotation is correct but the cut of the gears would be wrong for the front) and using the backside of the gear.  It would be stronger that the orginal front.

yes, its mikes idea we've built several of these since the first one, they work great, i was going to see if i could change some stuff and make some room for a little more  clearance.   the sami front is still a 7" r/p i was looking for more strength.  stan
