REPLACEMENT PARTS: SEE PAGE 185

NOTE: S&S does not offer a direct replacement cover for 1963–'64 engines with outside oilers. However, cover part #106-1619 is functionally compatible, but is not cosmetically correct for those year groups. Stock covers of the four ribbed design, and cover part #106-1619 is a flat-side design.
