I lucked up. I found these perfect industrial grade armrest on clearance. They fit any millennium seat "drilling required ". They can be adjusted for any angle you need depending on your seat angle. They flip up perfectly. They want last long get them while they last. $20+$2.40 for shipping.
Should I put this on another forum?
