51 3100 with a 59 235.I got an oil filter out of a 53 chevy school bus. Not sure what size 6 cyl.It has a mounting plate welded to one side with four holes. It was bolted to the side cover on the bus motor with the cover mounting bolts. My 235 has no mounting holes anywhere on the manifolds and the side cover bolts don't line up with the holes in the bracket besides being on the wrong side of the motor.I'm looking for ideas on how to mount this thing. ---Jack
