I have several mid-1960's Sportster front fork triple tree clamps and all have the welded and drilled fork lock plate on the bottom. When installed, this vertical plate matches the cast and drilled anchor landing on the frame. I know that these anchor mounts were on XL frames as early as 1962, so I assume that the '64 XLCH models had the lockable triple trees, but my memory is not what it once was and I'm second-guessing myselfe.
My Sportster parts book is a later one that runs through 1965, and it lists P/N 45701-54A as correct for 1958 through 1964, with a change to P/N 435702-57 in 1965. The casting number on the part, which is most often different than the P/N, is 45707-52A, so not much can be learned there. Besides, the lock plate was welded onto the part and not incorporated into the casting.
Can anyone inform me as to what year this lock plate was first used? I just want to confirm my opinion (and my memory of when I originally got the bike many years ago) that this is the correct triple tree for the 1964 XLCH.
Thanks,
Bill Pedalino
