Mopar circle track question

I thought the Valiants and Darts are only 111" wheelbase. I have talked to the owner of the track and unfortunately he is a mopar guy so he knows a lot about them and I know it will be tough to sneek some things through. They are pretty good about enforcing the rules. This class only allows a 2.76 or higher rear gear. They suspended 2 chevies for 30 days for having a 2.92 rear gear. Just wanted to throw that out there for talking about the gray areas of the rules.

They are. Will they let you move the rear back 1"? or is a stock wb required?
