Here are some super close-ups I just took out in the shop! Mind you, I have changed the hardware up a tad since that much older picture (like a new axle nut (lug nut) as well as a flange nut on the adjuster instead of a regular one. I think that was it for these components though, everything else is original.
Also, that spring on the adjuster rod is just a regular spring with round wire and it was original, best I can tell.
I might be able to get you some internal pictures, if need be, as I am going to have to put in a new tube soon and plan on checking out the brake system too while it's out. :thumbsup:
