P/N 55692-S is a grade 5 nut and is 0.292-0.302in thick. A grade 2 nut, 0.258-0.273in thick, is required, P/N 55672-S, per Ford assembly documentation and is not in AMK's catalog.
It's a picky point and will fit, but that the reality of what AMK offers.

I'm not sure what is ment by the AMK bulk section, but the exact locking nut is not listed. AMK has a grade 5 5/16-24 nut that is thicker than the grade 2 required. I don't know if that makes a difference. Be advised that the installation requires two flat 5/16 ID washers, 11/16 OD. All are clear zinc plated then covered by a medium-light layer of under-coating.

As an 'old' new guy to this forum, I'm going to ask the obvious - what year Mustang? And to verify what you are looking for, the two nuts that are attached from the engine compartment?

Greetings,
As the latest member on a forum of a very exclusive club, I would like to say hi. I have a 66 Fastback GT with a 'K' engine, a C4, Pony interior and factory original Styled Steel Wheels - just a basic 'K' car.
