Welcome to the fire, Savage99t!
Sounds like you need a set of mechanical drawings. I did see a set on e-bay one time, but that's been a while. Maybe Buck will will know of a source.
If you can lay your hands on a copy of Arthur Pirkle's book, Winchester Lever Action Repeating Firearms, Volume
I, he describes parts in great detail including thead pitch and measurements. Not sure how much use that would be.......
Another option would be to purchase aftermarket links, or see if you can borrow an original to take patterns from.
Sorry I can't point you to the plans, but good luck, and keep us posted on your progress!
