I have some friends in town with a 2001 Safari coach, 350 hp Cummins diesel, Allison transmission. Their driveshaft is toast. I removed it for them yesterday. It needs the flange that bolts to the trans output shaft and it needs new U joints for sure. The transmission flange and yoke wore into each other when the U joint started going bad. The trans flange is no good for sure, driveshaft yoke might be usable. Where can I get parts near Columbus Ohio? Thanks.
