So i bought a set of triple trees from ebay for my 73 cb500 four and they are NOT from a cb500 four as listed. No big deal, my stupid mistake. I was just in a hurry, and should have looked into them more. They cost next to nothing so im not too pissed, but now i have parts i dont need. Take a look at the pic, you can see that the top tree is not a clamp like a 500, bot solid w a hole through it so you can run a fastener downward. I dont know what there for, but if you do and can use em, let me know. And if anyone has a top tree from a cb 500 four you can spare let me know also.
