Thanks for the lead. I've also recently found another gunsmith shop both capable and willing to take the job. It was formerly owned & operated by the late Bob Dunlap of the American Gunsmith Institute videos. Pisco, AKA, Pacific International Service Company. I'm not quite ready yet, but when I am, I'll likely use them, $200-250 (+tax & shipping), with a 2-3 month turnaround.
Thanks, Karl, 68coupe
