Barlow,
In addition to Clarks, if you head over to Rimfire Central and go to "Ruger 77/22", you'll see one of the first topics is "Ruger 77/22 rebarrel." Theres a guy over there named 'nemohunter" who does exactly what you are looking for. I have no idea how good he is, but you might want to check with him and get a feel for what he does.
He gets stuff from CVlarks as well. Good luck.
