If I wanted to duplicate my seat that is all tattered and torn Where would I go . My Bike is an old Sears Rancher. 3.5 hp it had a white seat area with black along the sides . I still have the foam but I am wondering where would I get the material and what is the proper material . I am reliving my child hood and this bike is identical even in its color (green)to one i had 35 years ago. Thanks Kevin
