Seam Sealing Doors

As mentioned before Faxon reproduces factory assembly manuals that were only used in the factory during assembly. They have a treasure trove of information. You can find this one on Amazon or Ebay motors: 1970-1971 Plymouth & Dodge Electrical & Body Assembly Manual Dart & Valiant. It is 383 pages of diagrams and instructions, specific to these cars. I will scan a few pages specific to your car. Your body style (2 door Hardtop is referred to as "Model 23". You will find most diagrams noted as to body style (for example... " Model 23 & 29"), and if there is no style indicated it applies to all A-bodies. I'm not sure how extensive the work done to your B pillar (sometimes referred to as "Lock pillar". There is a brazed and ground seam in the rocker panel right under the B pillar. If you need that info just ask. Most of the sealing in the B pillar and door are from behind in the seams in the "Deadener & Silencer" section. If you open your trunk and look at the inside of the quarter panels you should see rough material like undercoat sprayed there. This is sprayed inside the B pillar and inside the door and seals the inside of body seams. It also is what keeps your car from sounding like an empty tin can. There is sealer where the quarter is welded to the lock pillar inside the door jamb. For each page there is a locator schematic with letters in boxes and then detailed schematics labelled with the letters. Scans to follow.
