For your consideration is an original Stover Rocker Arm, and the stand with the spring. I’m not sure which model it fits as I’m not a Stover expert. The number cast into the stand is, 8K6. It’s 3-1/8″ from center of the 5/8″ head stud hole to the center of the pushrod guide. It’s about 3-1/2 from center of the pivot to center of the adjuster. I can’t tell the part number of the rocker arm other than a K. The rocker pivots as it should. They’re in original patina. Please read the following full description so you understand the terms of the sale, this will save both of us time by not messaging me questions that are already answered. Please review the pictures and full description as what I’m showing in the pictures is the actual item you will be receiving, and the pictures are part of the description. The can koozie is used for a size reference, it’s not included as part of the sale. I do NOT allow offers on my listings. Thank You for viewing, John Tonjes Jr.
