All the stuff from the dump fit into the seat. I am still working on the seat back and have a few things to do with the gas tank before this phase is complete. Then pull the box and work on the back end. I filled up the cotton batting that was missing with parts of the uhaul pad and then topped off with the 1" foam camping pad. Carefully stuffed under the naugahyde and them stapled onto the funny steel tack rail around the seat base. I'm gonna say this tack rail is tightly woven horse hair crimped into a u shaped channel such as will hold a carpet tack and later re upholstery jobs like mine , the third, holds a staple. Yo re-use the naugahyde I stapled the pereimeter over the top of a string of electrical wire. In othger words , instead of shooting the staples directly into the naugahyde, I ran a string of lamp cord auound the perimeter and bridged the staples witrh my pnuematic stapler using 1/2" staples.
