I used Hyundai Tiburon leather seats $35 each from my local wrecker. I bought two pairs with the thought of getting a pair recovered at some point to match the 70 stitching? I love how they fit and are low enough especially to fit an E-Body. No heavy electrical junk
( nothing to fail either!) lots of adjustment. When I made mounts I took the opportunity to move the seat back as I'm long legged. Much more comfortable now.... and much more supportive in corners!
