if you look at disco's list for rearsets you'll see they list one specifically for cb500k 71-78. these should work.

I've emailed him before, seems like a decent guy. prices are pretty good.
Raask rearsets can still be bought through M&P in the UK or O'mars here in the states, Phill Little @ O'mars Cafe (763) 745-2255
the mounting bracket is a little overkill, big cast iron mount. but its definitely strong enough to take a crash or two....or three. and its just a bolt on deal, will take you ten minutes.
