In San Antonio, the best is Duffin Engine Service at 1227 Hallmark (just south of S.A. Intl. Airport), phone (210) 341-8183. Very professional and clean facility staffed with knowledgeable folks. They just R&R'd the small end bushings for my 300D and did an excellent job - min. spec. is .012mm/.0005" and I measured them (also checking to find out how good my measuring skills are) and all rods were exactly the same - .012mm! Give them a call and talk with them about your engine.

Good Luck!
Tom
