New to Mopar here..

Great looking Barracuda.

My -67 Formula S 383 got torque boxes in front of the rear leaf springs.
Wich I belieave only BB cars and converts had.
But then again, they could`ve been welded in also.
Would it be possible to identify the K-member to see if it got the BB K-member.

Don`t know about in the US but here in Sweden, at the time of the late
80:ies, no one would put down the effort to convert a -67 Barracuda to a -68 in that extension to replace everything that identifys a -68.
