What I can confirm is that John Tempest, Deputy Chief Engineer with the PFA
in the UK, is strongly against installing a centre pin. He feels that this
significantly weakens the sill. This combined with possible damage from
clumsy exit/entry would render the structure inadequate in the event of a
crash.

Since any "third pin" bushing would be located outboard of the weatherstrip
seal, how is water kept out of the cockpit?

The "receiving bushes" have a secondary advantage, they restrict the fore
and aft movement of the door in the frame.
If you have the Jonti Docker door mod, a half round peg that sits in a
recess in the lower door frame and restricts the door from bulging outwards
with cockpit over pressure, (when the ventilator is wide open) there's
almost no way of latching the doors incorrectly, easy with standard door
fit. Similar;y with Bob Jacobson's third pin.
Fit the extra bushes, they also stop the glass fiber edges wearing the
aluminum pins out quickly.
