I have been scratching my head on this one. I figure the car count will not be as good as the 29 in April but not 10. The regional teams will likely show up to add to the count. I would guess 18-22. My gueses:

Bobby East
Jerry Coons Jr.,
Cole Whitt
Darren Hagen
Bobby Santos III
Brad Kuhn
Caleb Armstrong
Dakoda Armstrong
Chad Boat
Brad Sweet
Brian Olson (REG)
Kyle Hamilton (REG)
Mario Marietta (REG)
Alison Mcleod (REG)
A.J. Fike,
Mario Clouser
Zach Daum,
Adam Kramer
Ricky Ehrgott
Bryan Clauson?
