Welcome to the forum.
Since I bought my 25 last October I have been looking for any and all information on the Oday 25. I have never come across such a list and doub there is one available.
Even if there was, I would be careful counting on it since a lot can be changed in 25 years. Your best bet might be a call to Rudy at D&R Marine. He used to work at O'day and be able to help you out.
If I was going to trailer my boat a long way to no where, I would buy kits, such as a kit of various size cotter pins, a kit of various size clevis pins, etc. Maybe try to find someone who changed out their standing rigging and by the old rigging or just buy new yourself.
Shackles, blocks etc shouldn't be too old to identify or at least find a right sized replacement.
Again, Rudy can supply a large number of what you may decide you need.
For the trip I would tape everything that could possibly come loose so it does not vibrate out and stay north of the border.
Enjoy
