-===== L1973-1978 Offset Mount Tank =====
-The design of the frame changed in 1973. 1972-earlier used a heavy rough casting where the top tube and the vertical rear tubes meet. \\
+"Add-on" to 1968 XLCH: \\
-The 1972 and earlier frame tubes are canted at an angle of 10° where the 1973 frame tubes are at an angle of 9°45'. Not a great difference but still different. \\
-did away with the casting. \\

-And used what looks like lightweight welded strap metal with an angular bracing running from the rear engine mount up to the end of the fender supports. \\
-But a greater change (apart from the casting elimination) is the distance between the head tube and the rear vertical tubes. 1972 = 28.42", 1973 = 29.04". \\

-Even though the 1972 frame head had a greater rake angle (30°) the \\ 1973 rake angle was less (29°35') the distance to the rear tubes is greater. ((piniongear of the XLFORUM http://xlforum.net/forums/showthread.php?t=806891)) \\
--78 tanks are notched on the flange between the top bolt holes. This notch allowed HD to raise the tank position. \\
+===== Mounting =====
-Raising the tank meant that both the upper and lower mounts also changed. \\
-In 75, a ridge was added to the inside of the filler neck to retain the filler cap better. \\ The 73-78 bottom mount is taller for the raised tank. ((Dr Dick of the XLFORUM http://xlforum.net/forums/showthread.php?t=1284627))
