I've been frustrated with the leaking spools on the original and reproduction 1968-1969 RS vacuum relays. These are non-serviceable units that cause vacuum leaks which result in slow or impaired operation of the vacuum RS headlights in 1968-1969 models.
I finally worked around and found an alternative. It is an electrically fired (12V) industrial grade stainless steel spool with buna O-rings that is rated for full vacuum.
I left my factory RS relay in place and tucked the new unit under the relay to hide it, then routed the vacuum hose to the new MAC relay. I wired it to local ground and then the supply from the common hot wire off the brights switch (on the floorboard).
It works great, the lights operate quickly (as designed), and I don't have anymore constant vacuum leak to the engine.
Anyone interested in this? I had to buy a few relays to try and have a few left over to sell.
I'll post some photos later if there is any interest.
