Slipperential question!

[rcjunky10]

Guys, I have just installed a slipperential in my SC8 and have one or two questions.

The set screw that gets threaded into the Adjustment Ring (AR), mine seems to be hanging out too far, so far in fact that it is hitting the chassis. What am I doing wrong as I have it threaded into the AR as far as it will go.

The top plate on the center diff will not install properly after installing the slipperential as the casing is too large. Have you guys simply modded the center top plate to work around this issue?

Thanks guys!
