Yeah, I'm in the process of switching over. I had the earlier style on and accidently bent the turn signal out taking a cover off the bike. When I straighten the turn signal out, the ear that the stalk goes into snapped off. This is an aftermarket piece and the ear is attached differently than the factory part. I happened to have a complete unit off the 74 parts bike I have along with a new lense that I had bought for my Bonneville. So for the time being that is going on. Since my bike is a very late 72 titled as a 73 I'm just going to have to pretend it is correct. This will also allow me to use the small light on my 71 when I get around to doing it, as it doesn't have any tail light now. Ah, the joys of a parts stash.
