I can't believe my luck. I order wiper blades from Crocker and they arrive and are great except they don't fit. The wiper arms on mine won't fit the replacement blades they sent. The replacement blades are narrower in the mounting area with a hole for a pin or something. The blades are slightly beefier with a much better construction. I think I got blades for a newer Marlin. I would like to replace my arms and go with the new blades. I assume they are an ANCO product as well. Does anyone have a part number and source to purchase them?
