-Oil filler neck is shorter than the -80 tank. It's not clear what the actual oil amount ​is for the 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. \\ 
 +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. \\ 
 +1973 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.

 +L73-78 tanks are notched on the flange between the top bolt holes. This notch allowed HD to raise the tank position. \\ 
 +Raising ​the tank meant that both the upper and lower mounts were changed (new upper mount - 62554-73 and new lower mount - 62555-73)\\ 
 +In 1975, a ridge was added to the inside of the filler neck to retain the filler cap better. The L73-78 bottom mount is taller ​for the raised ​tank. ((Dr Dick of the XLFORUM https://​www.xlforum.net/​forum/​sportster-motorcycle-forum/​sportster-motorcycle-era-specific-and-model-specific/​ironhead-sportster-motorcycle-talk-1957-1985/​126499-xlch-oil-tank-differences?​t=1284627)) ​
