I just insured my 66 C10 with JC Taylor. Their brick & mortar shop is in NJ but I found them online. I tried Haggery first but they said they couldn’t write (cover) me. J C Taylor gave me the 500,000 liability I needed for my umbrella policy with 30,000 agreed value for the truck. 365$ per year. Very easy to deal with online. The coverage is with Foremost Insurance
