Are you looking for a "blueprint of the track frame that would show all the hole locations and thread sizes? If so, that would be something you would have to ask your JD dealer if they can get it from John Deere.

Between finding some of the old holes and the holes in the crossbar you will most likely have to locate the holes yourself to restore them.

I would use weld build up and grinding to fit before shims for the rear crossbar area. If you want to shim it, the shims likely will need to be welded in to stay there.

The 3/4-10 cap screws that mount the rear crossbar brackets to the crawler housings are grade 8 according to the parts catalog, if that is what you are asking.
