I finally purchased me a 470 series, full air brake equipted COE, like I've been wanting. It's a 1952 GMC F473-30, 22000lb. gvw. Truck. It has a 302ci. inline 6 cyl., 5 spd. direct drive Trans., & a Eaton electric 2 spd. rear axle. Even has Factory Accessory shocks. Only problem is, I have to get it delivered from the "Great North West". See it here,
