I have a 91 HB KC w/5 sp. that the previous owner had installed aftermarket cruise and it works very well. Not sure what brand, don't see a name anywhere. The only drawback is there isn't an indicator light. A couple of times I've been cruising along and pushed in the clutch- revs to the moon! I haven't done that in a long time tho. The good thing about aftermarket is you'll get complete instructions. If you go the j/y route you'll be on your own.
