I'll go out and check the rear wheel.The front is a 5 inch,the rear is the same design,but I didn't actually check the size.They actually look to be in real nice condition,The aluminum is dirty,but not white from corrosion.Are those wheels something special?It looks as if it did have a jackshaft on it,there are two weld beads about 2 inches long on the frame rails from the engine plate back.There is another one in the rear center of the engine plate,that would have supported the center of a mounting plate.I may have the fenders for it too.My friend the scrapper that brought me the bike said he also picked up a box of metal there too,and he found a couple of little fenders in it.
