Also try early Chrysler Laser or Dodge Daytona seats.

I've seen a few of these with removable headrests but also some with high backs that aren't quite so high back like those of a 280z.

They are easy to climb in and out of and some of the higher end Daytonas had power options in the seats as well as switches installed on the inside seat cushions. Which would be real slick in a Rod.
