Dave Ray (IgnitionMan) posted this on another board. It outlines setting a Crane, or stock GM vacuum advance up with a Crane 99619-1 stop plate, to help correctly set the vacuum advance up for full manifold vacuum use. "I have 12 pictures and one installation sheet ready for the modification to either a Crane adjustable, or stock GM vacuum advance, using the Crane 99619-1 stop plate. If anyone wishes to have these pictures and sheet sent to them, or wishes to post them here, e/mail me and I will send them. sparkman451@earthlink.net Ask for "Crane plate pictures"."
