core support/trunk rail stamping

68 Dart. So far, all i can say is that the rad support and the trunk rail came from the same car.:lol:

Vin on engine (340), transmission (4 spd) and the dash all match, but don't resemble the stampings mentioned.
engine/trans/dash: LS23PB278340
rad support/trunk: B8L119063

I came to the conclusion a long time ago that the car is a bastard, and I'm gonna' build what I'm gonna' build. It would just be interesting to know more about its origins.
