Those PUI foams look good to me, but I've only worked with Legendary foams and covers. You've probably figured out that the leather seat covers get a different foam than the standard vinyl seat covers do. The foam with the parallel straight lines are for leather seats. Our Cuda came from the factory with the optional leather seats so we recovered the seats with the same, so I'm including a photo so you can see the difference.
Be advised that if you go with the leather (once you've adjusted your hem), you need to cut another groove in the foam across the front to accomodate a (wire) casing and row of buttons. Neither the PUI or Legendary foams come with that slot.
