It has a 290 Cummins with an Eaton Fuller 8LL. Tires are all very good. Just drove it to tire place for a new tube. Inspection is due this month and the only thing I think it need is a directional. I have photos I can send you.
My 1964 Brockway wrecker was originally a triaxle coal truck. If you wanted to remove the booms and put a dump body on, she would serve you well. See my ad under Brockways for sale. You can email lindachristy@atlanticbb.net for further information.
