Oklahoma diesel shop

Heading to Arkansas on a business trip. Wondering if there's any badass diesel shops that y'all know of that I should stop by on the way in Oklahoma or Arkansas.. Don't worry about saying BTS because that's where we're headed to pick up 7 4r100s.. Any must see shops out there?op:

Maybe a lil out of your way but baillie diesel in nixa mo brand new building. Check us out at bailliediesel.com

Not really. Your going to probably the nicest shop around, BTS has a really cool setup.
