I have a RV6 with an old Skybolt cowling fastener kit and I am now missing two of the fasteners. They are the -0 length. It appears these have been replaced with a newer design. Skybolt customer support says that the new SK40S5-2S will fit the old grommet but the length of the old one is .620 and the shortest new one is .690.
Has anyone replaced one of these with the newer ones? Or do you know of any direct replacements?
