One other suggestion... if you stay with the #7 take the valve stack apart and rearrange the valve order to convert it from the retarded ISO pattern to the SAE pattern.
Is this a personal preference based on backhoe operating experience, or just common sense? I have never ran a backhoe, so I wont know the difference either way. And if is just personal, I will probably leave it match the decals under the the levers, as they will be new. Im gonna look into the difference in between the two configurations and if it seems like the obvious choice, im gonna look for a newer JD decal that matches the SAE.
