Sioux model 672-A Rocker Arm Grinding Attachment
This attaches to a Sioux valve grinder so you can set rocker arm clearance after a valve job and/or head resurfacing.
This is generally used for older cars with shaft-style rocker arms.
Fits Sioux valve grinder models 645, 682, 662, 657 and 655 and possibly others.
This looks to be an NOS part that was never used.
Rare to find a new one with all the cones and other parts.
$95 plus shipping. Paypal OK.
