Will 70 Dart V8 K-member fit 65 Barracud?

To increase strength, Have the entire perimeter of the "K" member welded. It is 50 + years old.

He's got an early A body. There isn't a defined perimeter that can be welded on the early-A k-members as there is with a 67+ version.

You will also need a V8 center link for the steering.
