Summit output shaft diamater??

[FireWire79]

I am going to be installing a Summit tranny into my SCX so that I can get a little speed out of it and have a question. What is the diameter of the Summit output shafts vs the Axial axle shafts?

Do I need to do a custom number to get these to match up or can I do it with Stampede shafts, or Summit shafts? I am just curious and need to make plans now as it takes a while to get parts in Iraq.

Also, if anyone can link to something that is pre-made and ready to rock for this issue, it would be greatly appreciated, as I have access to very few tools here in Iraq as well. If not, let me know what I need to order to get this pony on the road.

Thanks in advance.
