Yeah Charlie, now that you mention it, I do remember when I bought my first 300D T a long time ago, one of the very first thing I did was to fix the truck lock vacuum actuator. I remember taking the vacuum motor apart and used wet suit urethane repair adhesive (Aquaseal) on a punctured diaphragm. It is still working fine to this day.
