What pattern do the 7.3's use?   Is it an SAE pattern, or something proprietary to eithe rFord or International?   I assume it is the same as a 6.9, right?

Needing to replace the OD in the second of the F350s and I would rather do something less expensive then the reman in the first one, and hopefully a permanent fix. 

Have availible an MT545....wondering if there is any way that can be practical.  Otherwise would consider a C6 if they exist.
