Looking for the same thing for my Cat 416 Series II extend a hoe, just bought it at a good price, for some reason it has Case controls,5 sticks and swing pedals, which are sticking and hard to centralize. I've for the last 44 yrs. ran mostly Cat equipment and can't seem to get used to the sticks, I believe the wobble sticks are so much simpler, although I have ran mostly Cat hoes and excavators, even the Case 680K we had had Cat wobble sticks. i'd swap the controls from my 416 with anybody that had wobbles sticks in a heart beat.
