73 thru 76 A body disc brake LCA's w/ swaybar tabs

Numbers are on the rivet heads.
One is the number day of the year.
The other is the last number of the calendar year, the shift that it was produced on, and the line that it was produced on.
Hi Jim, thanks. By the way we know each other. I sold you some small bolt 4 piston calipers many years ago. I remember seeing you at the Hagen park show when you had the GTX. Last time I saw you, you were talking about selling it. May see you at the show this year. Haven't looked up the dates yet but am planning on going.
