Take video and a 1000 pictures of EVERYTHING.

Bag every pce and every nut and bolt in a properly identified bag or container.

Get as much literature as you can including the factory parts manuals and maintenance books.

Figure out what parts and do-dads get finished in each type of finish and divide them into piles for sandblasting, media blasting, powdercoating, painting, plating, etc.

Then make a list of stuff you need and start researching where to get it from.

Save stuff even if you don't plan on reusing it and consider rebuilding original components where possible over replacing with generic rebuilds and repops.

good luck,

Dave
