Same thing with my '77. I finally cut a small access hole inside the air intake (removed the intake cover). One of the nuts vibrated all the way off and the other has a rust build-up so I can't tighten it all the way. I will be installing a new bow eye next week. It is kind of like building a ship in a bottle, but it is do-able.
Two Chrome 10 hole wheels with Kenda Loadstar radials.
Mounted, balanced and delivered.
