picked up 1972 dart 340...............real?

Yes. Vin matches the rad support and drip rail on trunk. But do not understand the b in vin for where it was built as I thought all 72 340 dart were built in Canada. B shows it to in Michigan.

B is the Hamtramck/Dodge Main plant...

They could have built a few, they are not far from Mound Road Engine plant that built the small blocks as far as logistics go...

How you been Joe?
