Thanks Bob. The pan # matches the body #, unless they changed one of them? The body # is a riveted plate in the right front fender and the chassis # is a small square tab on the hump under the rear seat. Is that number usually on an added tab on the hump, or actually stamped into the hump? I could take and post a picture of it tomorrow. It looks pretty original, not a later transfer. The trans is a 3 speed true automatic. Is it possible to switch wheels from wide five 4 lug on an older pan?
Edit: I just looked on the Samba and found a picture of a chassis vin plate for a Type 3. Mine looks the same. At first it appeared as if it was a blank tab, but I used a wire brush on a drill and was able to reveal the number, same as the one on the body tab.
