I've got 2 IO Port seat back braces for sale. After I started building the car, I realized I didn't need to be able to adjust the seats, so I just welded in braces instead. They're in the box, only opened to verify the contents.

They're the same as the ones sold here:
I/O Port Seat Back Brace-Stable Energies

It looks like I/O Port doesn't have the same version on their site anymore, but they were $100 ea. new. I'm asking $80 for 1 or $140 for both, shipped inside the lower 48. PM me if you're interested.

 

I'm interested in purchasing both seat back braces, but can't PM yet. Message me your Paypal address if you don't mind. Thanks.
