Need header ID help..

Lol, trust Me, I'm 'bout f*@king crosseyed from doing searches. Didn't think it would've turned out to be this difficult at the outset, that's a fact!!
I can tell you this much from looking at the driver's side. When the driver's side has #1 tube up and over 3&5, those are usually car headers. Truck headers have the passenger's side with the #2 up and over 4&6. If that helps any.
