Brian:
I did call MPI and the were way high. Got a 72" cat II, which looks just like yours, except they put the handle on backwards. It was about $2300.
Actually, had some problems with the skid steer stuff. Have to do some more mods on the bucket to get it to work, but rest of skid steer is doing fine.
Also, I added tilt to the 3pt from CCI. First time I used it I busted the anti sway bar in half. I adjusted the tilt all the way in and then lifted the 3pt. The sway bar hit the backhoe mount and crushed the bar. Called a couple of dealers and looks like about $160 for a new sway bar, can you believe it? So, have not used the new Gannon blade yet and can't put on my bucket. But, should be all fixed soon. Do you have your hoses coming straight out from the tilt to the back or have them turned? Can't figure out how I can use the top link holder when not using the 3pt with the hoses in the way.
