Thanks to all who responded both off and on line. The update is 1 week of soaking with Aero Kroil, 1/2 inch drive impact and about 20 minutes this morning and both of the anchor pins spun right out. Did take a dremel and clean up the areas where the washer was folded over on the nuts. On to the master cylinder !!! -Rex- 65 Vert 61 Rampside (project)
