Well, if you casually say "I replaced both pins yesterday", then that gives you serious street cred in my books ! It took me a week to do mine, they'd rusted solid and turned out to be one of the most difficult jobs I've ever done on any car. (rust, access, rust, making spanners, rust, scraped knuckles, swearing, rust...)
Mine were original and had a split pin through the hinge pin, just above the bottom nut assembly, which stops it falling back out and onto the road.
I had some advice from a local Lotus specialist at the time who told me the biggest problem with Europa doors was that the pin seized in the nuts and then opening the door turned the pin itself in the body mounting. This wore away the mount and you could never get the doors right without replacing the body mounts. He must have seen a few because he'd designed a brass bush insert that you could fit into the existing alloy body mount which he used on his restorations.
Anyway I used a stainless rod which I pinned above the top body mount (you get to through the front wheel arch) and fitted a square plate so that the pin itself can't move within the body. Now all movement must take place with the pin static and swiveling on the steel nuts in the door as originally designed.
I can't comment on the ability to tilt the door because all I did was replace mine with the same sized spacers and washers that it came with, bolted it up and it fitted. (eventually)
Not one of Chapman's better ideas but probably very cheap at the time.....
