Mine's up in October - with Farmers and I have similar concerns on my 65' C10.
I'm shopping everybody presently - classic insurers and regular companies alike.
I'm spending about $300 every six months for my 1/2 ton and when I told them I wanted to insure the truck for a set amount (because of the butt-load of cash recently invested therein) they balked and said I'd need to get it surveyed by a certified appraiser - at my expense and submit that report before they'd even look at insuring for more than a "regular 65' Chevy pick-up."
I'll be driving mine about 75 miles a week on the street and this insurance thing is extremely irritating. I'd be interested in some input too.
Mac.
