The Vin number tag on the windshield, Make sure you get it also I slid mine under the speedster windshield letting the numbers show as before. It looked perfect.
The 77 will have a side inlet on the tank that would have to be sealed up Way to much trouble for the average builder Let it go or sell it Best to buy a New ghia tube type fuel sender your gauge will thank you. that will prevent the bouncy gauge needle mess.
Best to get a NEW 16 gal CIP-1 tank,, A new super beetle speedo cable. and do run a internally controlled Alternator
I'd save the steering column It can be converted to look early.. The brake reservoir and lines. The horns,, All the body bolts. ,,The old speedo cable rubber spindle seal and E ring. The wiper motor assembly wiper arms I like the newer 1970 center bolt type wiper arms ,married to the 1961 10 inch wiper blade they are a stronger than factory combo. The seat belt stuff Just in case. all the dash bulbs and holders. The pull type light switch if so equipped
The fenders,doors and lids can go to the Samba ads Even the seats. head lamps and tail lamps will sell good also the mirrors even the sun visors
Save the license plate light kit from the housing on the lid...It can be turned into a trunk light kit. It makes a nice one. Just add a slide switch to it.
