I bet the following drivers likely wont have any other commitments and will run up front.

T-Mez - No explanation needed
T-Mez - No explanation needed
Max McGhee - If he's not back in his dad's car I mean Sam Mcghee Motorsports car
Modern Day Cowboy- No explanation needed
Possibly JG - If he can get away from the kids
More T-Mez - No explanation needed
Macedo - If he's available, solid runs out west and THAT
tt - likely available
Bernal, maybe huner% if he's not wanging it, the throttle if he's available, or just see whos out of ride by then. Never know where these wheelmen will be by 8 months from now
