Norton 920 piston rings

Hi does anyone know where I can source piston rings for my 920 Norton engine, The pistons are AE, the compression rings are 1/16" thick, the oil control is 5/32" and 2 piece, the bore size is 80.9mm , the wrist pin 13/16". Thanks

Try Total seal in Phoenix Arizona. 1/16, 1/16, 5/32 are common sizes.. They just need the boer size.
