Picked up a Stampede 4x4!!

I was looking at these Slayer shafts http://cgi.ebay.com/ws/eBayISAPI.dll...=STRK:MEWAX:IT The diff side is easy, just switch out to Revo outputs. But it seems like the axle end wouldn't work with any available axles, maybe you have a plan. When I get my Tekno's , which the rears use a bigger inside bearing 10x15 , like the front, I'm going to see if they can be milled out to use a 12 x 18 bearing, which would then allow the use of the complete driveshaft.
