They were a conical head, cadmium (NOT zinc) plated, stover-style, distorted thread, 7/16-20 lock-nut of GM 301M material grade (SAE grade 8) and of GM #9422300. They were discontinued from SERVICE several years ago.

Finding a locknut of the correct configuration/finish appearance is quite easy. Finding one of the correct configuration/finish AND of the correct material grade is NOT so easy. What makes it worse is that these nuts have critical safety implications and a lower grade nut must NOT be substituted.

Do not use hardware store lock nuts. They will be of ungraded material and WAY too inferior to use for this application.
