These are the Procar lowbacks in my 60. I'm going to diamond tuft them soon to match the rear panel and door panels, but remain as comfortable as when they were first put in many moons ago. They're relatively cheap, have adjustable backs, and hold up really well.
You can even get them thru Amazon now, almost $20 cheaper than Summit and the shipping is free:
