One more thing I suggest. Here is a
LINK to a picture of some GM replacement rocker supports. If you look closely you will see these have a slot cut through the support at shaft level. What this does is make the support pinch down on the shaft to prevent the shaft from rocking in the supports.
I make my own with my Sawsall. There are three supports per shaft, I do this to one support per shaft.
If you click to the next picture in the link you will see one I made.
