we are restoring a 1971 cobra jet for someone else. The car has already had restoration work done before we got it. I dont have anything to use as a guide but a old rusted out parts car. We have put all new metal in the rear. I need to know about the factory spot welds and where seam sealer goes and what it should look like. Then where and how does factory undercoating and paint should look under the car and in the trunk area. Do you know where one could get a good guide book with pictures. Thanks so much.
