As some may have pointed out already. No shims typically end of life is near for that rod or main cap. If it specs out ok then there is more life in the part in question. Personally if is already apart I would fix it before moving on.
FYI....Berts shows these hinges now on the website. Upper middle and lower. Door post and door 40 bucks each, if you still happen to be looking. USA made!!!
I am doing this to some door for a 30 as well. I was wondering what the final outcome was with your door. Did you locate rivets and use them or did you go to screws and nuts? Very curious to know. Thanks Rick
