the seat is half Cb360 gas tank / half lowes sheet metal. i layered the inside with fiberglass to make it stronger and resist bending. the upholstery work was down locally by King's Auto Upholstery.
www.kingsautoupholstery.com 540-344-0718. pricey, i paid $170 for the upholstery job and actually changed my mind and called them to come pick it up before they had got started. my message didn't get relayed and when i went to pick it up they had it done. but i was so happy with the way it turned out i didn't complain. I don't mind paying a lot of money if the job is worth it. and i liked supporting my local community at the same time too.
but they are good people and do good work.
let me know if you end up sending a seat to them to do. And tell them that the guy with the red motorcycle seat sent you so maybe i'll get a break on my next one.
