yes the front derailleur body will have more of a three sided triangle as opposed to the extra side on the one on the bike now. There will be no protrusion in the front of the aluminum body where the pivot stud is either. I think at least one of the arms will be chromed brass still in '69 if not both, and it goes without saying that there is no C-clip on the upper pivot to hold the arm on. There were also variations in the derailleurs which has the cable housing stop... if you do end up with one that does have it, it should be the slotted variety, the first ones did not have a slot. A local acquaintance of mine has a FD from about this period, but I think the condition is fair. I think it is also missing the clamp bolt, but that is easy enough to replace. I can look into it if you like. Send me a PM. But if you are going for a real full on resto this piece will not be up to snuff.
