I have 4 skoolie seat frames (2 left, 2 right). I also have the 2 from barriers.
They've all been completely stripped down to bare metal. I'm planning to chop them up to harvest for raw materials, but if they will help someone else move forward with their project I'd be happy for you to come pick them up
The seats are currently with my bus on Treasure Island, San Francisco. Reply here or shoot my a PM.
