Ive seen Carshine Bob's work at MCACN - Jimmy McKeague's blue 1970 W-31 was off the charts magnificent. Badgleys have been doing Hurst/Olds and other Oldsmobiles for many years as well and have a good reputation.
I've seen several Garner and Thornton-restored W-cars at MCACN, Nationals and other events. They're always very, very nice. I'll recommend Bernie Karhoff in Lima, OH too. I've judged a couple of cars that he has done at MCACN and elsewhere and he has the eye for detail of an Olds specialist too.
