Mikeg103 I go to the fabrick store buy a canvas type material that is kinda stiff,my wife can sew that so the joint wants to be L shaped,use your old cover for a pattern,on a 51 3100 that cloth is held with clips that don't hurt it like hog rings. Change out weak springs,pad with new foam tied in place so it wont move. on beaters if it wears thru you can turn it inside out and go some more,like on a wood hauler. Make you some cardboard patterns of seat top and back to work off of they are easily changed !!
