This is not a new problem, any number of owners of early cars experienced the same issue, myself included. The problems lies with a thick weld bead at the bottom of the strut tube that prevents the KONI insert from fully seating. The problem is visible when the gland nut will not install to the correct depth. KONI and MSA worked on a solution in the form of revised gland nuts with a longer thread body. MSA supplied these modified gland nuts at no cost to customers reporting the problem. I recommend you reconnect with MSA and request the modified gland nuts. BTW, the problem seemed to be limited to the front struts as there were no reports of rear struts having the issue.
