-This is a rebuild of the stock Delco Remy horn from a 68 XLCH. \\+There was a truck load of changes in the horn mounts between late 1970 till 1975. ((Dr Dick of the XLFORUM http://​xlforum.net/​forums/​archive/​index.php/​t-1492366.html)) \\ 
 +The changes weren'​t really cataloged in the part books. \\ 
 +Basically: \\ 
 +1965-1970 all used the same geometry. \\ 
 +1965 and 1966 used different stuff than 67> but the end result was same. \\ 
 +And this 1st gen stuff was used on some 1971'​s,​ maybe even some 72's also. \\ 
 +This set up used the larger diameter, short, stiff, 5/16" stud rubber mount. \\ 
 +It held the horn way more solid than the later smaller, longer, 1/4" stud rubber mount. \\ 
 +Both 1st gen brackets had less inward offset than any of the later ones. \\ 
 +The shananigans began in late 1970 with the intro of the '​low'​ seat kit. \\ 
 +1971 and maybe the 1972 bikes that came from the factory using the older standard seats supposedly came with the 1st gen 65-70 setup. \\ 
 +In late 1971, the low seat was available factory installed for the 1st time. \\ 
 +The low seat required the ignition switch to be moved from the right side under the high seat to the left side on top motor mount where it fouled the horn brackets. \\ 
 +At first, the new brackets with deeper offsets that opened up room for switch were supplied that used the old 5/16" rubber. \\ 
 +There were some issues with interference. The smaller rubber mount and another set of new brackets were furnished to solve that issue. \\ 
 +But the 1/4" rubber mount let the horn flop around to much hitting fins and/or shaking the wire loose from the slip-on terminal. \\ 
 +The bumper was the fix for this. This 3rd gen setup was used till 1974. \\ 
 +In 1975, a bigger ignition switch was used. New brackets again, 4th gen. \\ 
 +There are so many different brackets used that having mismatched stuff is common changing horn position to who knows where. \\

 There are horn rebuild kits available, but they are pretty simple in design and a good cleaning may be all that is needed. \\ There are horn rebuild kits available, but they are pretty simple in design and a good cleaning may be all that is needed. \\
 The repop one from J&P Cycles is on the right (3rd pic below). It has 2 wire connections as opposed to the single wire connection on the original horn. \\ The repop one from J&P Cycles is on the right (3rd pic below).
