How about a sealed diff for the SLASH MIKE?

Hey Mike - how about building us a sealed diff for the slash. We race three of them and keeping diff fluid in is an impossible task. And you need diff fluid or they are all over the track. seems to me that you could put something together using the stock gears but with seals and sell them for a pretty penny.
Do the math on how many Slashes are out there now - its incredible.
