the factory never offered 15incher in a 4"boltcircle, nor do I recall ever seeing those Roadwheels in a 15 x 4" bolt circle
On the front of the Barracuda, You want a zero-offset, 14x5"wide or 14x5.5" wide wheel.
That 5" wheel originally came with a 695-14 tire or a D70-14; which in metric is about a 195/205
The 5.5 wore an E70-14, which is about a 205/215
