'70 Dart 392 Project; what direction?

Not sure what rules Procar is playing by but if this is a $91 vehicle specific “adapter” color me unimpressed. Website said both were in stock (driver and passenger side). Just received a box with no invoice or product ID and only one adapter.
Clearly the wrong one…. Just called, talked to a guy for 2 minutes who said “let me transfer you to another guy who handles online orders” which turned out to be a voicemail machine…. Great. ‍♂️‍♂
