The Stovebolt Site Forums The Parking Lot Panels 'N Burbs suburban seats - how much $$

I have joined the ranks of needing the center seat for my 52 burb. The National Guardsman who worked on and rode in it in the 60's and early seventies confirmed it had all three seats. he always rode in the back and climbed through the center seat. how do I find the link to the frame maker? I can do the upholstery handily. Thanks guys
