other than buying a set of CR's, i'm sure you could make a set of the PD carbs fit. i'm working on mine right now. they're from a '77K and going on a '76K motor. i had to get the '77 intake boots, but i found a good set on ebay. hopefully with a little massaging, they'll fit just fine! the benefits to the 77's is they have an accelerator pump and adjustable needles stock. i hear they run a tad lean, so i'm going to jump up a jet size. hope this helps!
