You can always stick description of your other rides in your sig, and in your profile's 'Garage' pics. It's also allowed to find a vague unrelated point in a thread somewhere, and claim that it "reminds me of something the same as this part of my other car", whereupon you post a pic of said non- B-body - in a real subtle manner than none of us will pick up on.
See, we have solutions for every complex problem in life. So, what's this POC you're driving now?
Final thought: You can try a pic of a Ford plowing into a lot full of MOPARs. It may not win anything, but we'll appreciate it anyway.
