Here's the story ...
As I have listed in the KFOCI HANDBOOK on CD item on 1951-1952 Vagabond Henry J's, When Confidential Bulletin #73 (Direct Dealers series: #70 in the regular All Dealers series) Accessory Group's 17 and 26 (4 cylinders) have Deck Lids among its items...17 also had fold down rear seat back, 26 had fixed rear seat back. You could also get a 4 cylinder with no Accessory Group (so no deck lid) if you wanted a bare bones version. If your 6 cylinder Vagabone was equipped with Accessory Group 8, you didn't get the deck lid; Accessory Groups 24 and 25 featured a Deck Lid with fold down rear seat back (group 24) or stationary rear seat back (group 25). When the cars were announced to dealers, the documents stated that the Continental kits were an option, at around $94.00 including Federal Tax. The kits were also offered by dealers as a dealer installed option. Accordingly the dealer-installed price might be a bit higher depending on service department labor charges at the dealership. For the 1953 model year, changes to the rear bumper area made the "older version" kits arder to fit and were not recommended for the 1953 and 1954 models.
More information on this will be found on the CD, including the Parts & Accessories bulletin on the item as a dealer installed option.
