Where can one get there hands on such material?? I made a template out of cardboard and was gonna either make it myself or see what my options were.... I got a local welder that can git 'er done, just had them cut some nerf bars down for me for my swoop body.... One of my older karts has a floor pan made out of stainless aluminum or something....You can make a floorpan out of high density plastic sheet, 1/8" thick. Have done it several times with several different chassis. Can use a heat gun to form the sheet the way you need it. The part where you would have to weld on the chassis would be the only concern I would have
