Hey from Oklahoma!
Former Ward, Am-Tran, BlueBird dealer/mechanic/parts guy here! (I even worked a short stint at the IC plant here in Tulsa)
I worked in the business from 87-96 and my dad worked from the 60's (delivering buses) until he passed away in 2012 (dealer), so I MAY have info rattling around in my old melon that might help in dealing with bodies, wiring and parts. Grew up around the Wards and Harmons (If you are a Ward/Amtran fan, you know!) so when I bleed, it's school bus yella!
