STUD ROCKER COVER SHORT
Short stud that secures the rocker box cover to the cylinder head, also known by its legacy numbers T66 and 57-0066.
This is the short rocker cover stud, 68-0143, used to hold the rocker box cover down on the cylinder head. It carries the legacy part number T66, later renumbered 57-0066 before landing on the current 68-0143 designation, so if you're working from an older parts book you may see any of those three numbers for the same piece.

Studs like this thread into the head and let the rocker cover cap over the top, sandwiching a gasket in between to keep oil where it belongs. Because it's called out as the "short" stud, there's a companion long stud used elsewhere on the same cover, so when you're ordering make sure you're matching the right one to the right hole.
We don't have more detail on this one beyond what's in the description, so if you're not sure which stud position you need, give us a call and we'll help sort it out before you order.
