I purchased a 1960's v-drive drag boat and was wondering if anyone could tell me if it is a Sanger or not. It has a pontiac 400 engine, casale v-drive and hall craft drive gear. The motor plates and exhaust are edelbrock. It is 18' 11" with the cav plates included. There is no manufacture id on the rear transom outside, nor on the stringers. There is a black epoxy type coating on the transom and sides on the inside, so you cannot see any numbers there either. The title says it's a wellcraft, but wellcraft did not make drag boats!! Any help to identify it would be appreciated!! I am adding links to the pictures.
