Thanks Chris, those look like the later style.
The 65's had the screw-in bushings that were only used for a short time....64 and 65 I believe???
The shafts are hard to find. They're repo'd by Rare Parts, but they're expensive and maybe look different than the originals??
I have some nice 66 arms I can use, but I prefer the correct '65 ones if I can find them.
