I have a B3030 with a BH75 backhoe. I want a thumb, but unfortunately, it doesn't have the dipperstick upper mount. I figured I'd start with the Kubota BH1976 Mechanical Thumb, and can always add hydraulics later. I took all the dimensions for the placement of the mount on the dipperstick, off of a BH77, and made a paper template of the side plates. I'm going to make a filler plate for the recessed area of the dipperstick, and tack everything together with the thumb positioned in the upright, non-used position.
I figured I'd throw the thumb on, and it took all of 30min...really easy! I used the old pin to hold the thumb on the outbound side to keep it positioned while I drove the new pin in.
It will be a couple weeks before I can get to this, so I'll update as I get things done.
