forgive if I post in wrong place. With a completely disassembled new purchase, I just dropped some $ on "1974 Chassis Service Manual" hoping it would have undercar schematics of park brake. While I'm still confused about terminology "connector" between rear lines and intermediate cable, I'm more confused about the legends in the shop manual (B, J, R, W, V, L, P, D, C)? What are those legends? I guess I'm dain-bramaged and was expecting to see something like "e-body" as a legend? Is Challenger C, and D is Dart and V is Valiant and B is Barracuda, etc? Sorry, I bought the books and hope to be as independent as possible, just need confirmation as I'm trying to learn more about Chrysler products. Thx!
