Hey Wild Cherry!
The funny thing is I had a certain owner of a certain track

rebuild the diff for me. He wasn't there at the end of the week last week so I couldn't pick his brain and I didn't get in today. So, tomorrow I will see if he can fix it and answer my questions. See what happens when a guy tries to be a nice guy and fix a car for a person.
That Edit diff screw would be awesome but it says it's not available yet.
