I played with test fitting my RX8's seats in the SA today. I must say they sit hella tall! I thought about buying a pair and fitting them into the SA, but now Im not too sure. They look badass and are comfortable, but they sit probably 2-2.5" higher than my lowback FB seats.

My number one favorite RX7 seat is the s5 black with red pin stripe seat. I had them in my s5, and had a pair briefly in this SA and the driving height and posture is perfect.

How do FD seats fit in a 1st gen? Is the bolt pattern the same as 1st gen and FC? Anyone have pictures?

Those seats are what the current owner, Bruce, put into my old TII swapped FB. You can see the height and fitment below:

 

RX8 (manual model) in mine! Driver side no prob for headroom (me: 6'1"), pass. side a bit higher tho due to the exhaust hump in the floor, as you may have noted. Need non-oe seat mount brackets to make the conversion. Fab look, very comfy for me a shortish passenger.
