+-E1965 adapters use gasket (32522-37). ((DR Dick of the XLFORUM http://xlforum.net/forums/showthread.php?t=1637862&page=4)) \\
+The parts catalogs say the gasket was available for 1958-1969 XLCH. \\
+However, gaskets are known to lose their structural integrity (used on movable mount systems) resulting in the hub working loose from the cover. \\
+HD got away from the gasket in mid 1965 for this reason. \\
+So L1965-1969 setups don't use a gasket. \\
+A bike with no seals barely leaks because the mag drive gears don't get very much oil. \\
+The oil they do get is "splash" oil. A very small amount of oil gets to drive gears by oil passing thru #2 cam bushing. \\
+**Screw and Washers**: \\
+The 2 big holes on the 62> mag lower housing slots are access holes for 2 of the 4 screws that hold the lower mag housing to the mag body. \\
+L62-64 had rectangular 'washers' that straddled the big holes. 65-69 had the arm that control cable attached to that straddled the holes. \\
+Uses #12-24 x 15/32" countersunk flat slot head screws (1865W) to hold plate to cam cover. \\
