I use Haggerty for my Vette, Harley, and 1957 Chevrolet 2 ton. When I called and talked to them about the '57 they got back with me and said they had nothing in their system to compare it to but would be happy to help me. I have an agreed milage and total loss policy. The company is very easy to work with and they are motor heads.
