Stretched tanks and a stock seat, What to do? On this Harley Davidson Street Glide, we took the factory seat and made it fit into the custom stretched tanks by molding and adding plastic. After the seat pan fit well it was time to move on to the foam mods. Because the front and rear riders were comfortable we only had to modify the parts of the foam that met the stretched tanks. After that came the fun part, build a custom seat cover. We decide to use a imitation leather for durability and the customer wanted Faux alligator down the center. We also added a thicker brighter blue thread to make the seat pop. Because of the large amounts of skulls and flame artwork on the Bagger we decided less is more with the seat.
