I noticed over the years that there is a lot of wear around the camloc fasteners. I found the skybolt website and spoke with someone. I guess they send a kit and let you pick and choose the ones that fit. Has anyone tried them. For $300, I'd like to get some feedback before buying them. Also, I have a 201 cowl, but no serial # to the plane that donated it. There are 2 packages available for 201 mooneys. Anyone know the differences in any of the 201 cowls (serial #'s 0001-1458 and 1459+)?
