1959 GMC 100 Brakes?

[mog797]

OK so this is the deal I am still trying to just get this thing to run drive and stop. The first one is good second tbd, as the third is not there yet. I am going to keep brakes stock as its quickest and easy way to do it also $ come in to play big time on anything I do. I am a disabled vet was retired by army at 29yr. old for a fun time. Anyway I rebuilt my master cylinder and was about ready it install when I realized I was missing parts, master wasn't on when I got the gmc. I don't have the shafts part #3719611 that holds the lower part of brake pedal in place on the brake master. Also missing is the retainer part #3712797 I am missing all the nuts and bolts but that I can deal with. Dose anyone have the parts from an upgrade they did or know if anyone makes them? Or any ideas on what I can do to make this work? I am so close to driving this pickup down the road! If I don't get it done soon it's going to have to sit outside over another Colorado winter cause I can't do the cold well!
Thanks for any help in advance!
