There are three corroded seals on the external gearshift lever on my 99 R110RS. One is on the ball pin that attaches to the shift lever part # 23411341575, one is is on the selector rod, part number 23411340306, and the third is where the slector rod attaches to the other shift lever, part #23411340415. Problem is I can't locate the part number in the on-line catalog. Any help identifying these part numbers would be appreciated. Thanks.
