There are plenty of places to get the 3.55 but it seems to all come from Patricks..some are less $$ though.. You will need the install bearing kit too...more $$ but it will pay off I think... I am a believer that if it sounds like it's about to come apart..it is and will. My 235 high pressure oiler sounds fine at about 2700 which I think is about 55 mph. Tim said 3000 m/l is cruising but I'm not happy there..or my ears aren't ... and, to date, I don't need the extra mph.
Edit: Just for the record, Tim is a master guru and really knows his stuff...nice guy too.
