Does anyone know the part number(s) of the brake cable/speedo cable lower support bracket attached to the front fork brake side?
Also the 1/4" - 20 (24-28?) engine mounting bolts? I measure them to be 1 3/4". Also are the bolts CP 1034 or CP 1038? I can't find that info in the Parts book.

I found the part number for the cable support... it's #10006 on page 51 with the 'wiring'.
Speaking of wiring. Do the horn wires exit where the throttle cable does on the handlebars or do they continue on and come out the center and run through the triple trees and exit out the bottom?

I know this is a month old and you probably already discovered all wires run through the handlebars to the steering neck and out the bottom of the triple tree.
A good source for how things were/are done is studying the large assortment of photos supplied by Jerry Hatfield's collection of H-D advertising photos as shown on the How To Restore page.
A great source of prototype pictures indicating what production might have been. Deductive reasoning can also play a part on deciding the proper way to proceed.

Thanks for getting back to me. Yes, I did find out the info I needed. I did, however, forget to look at Jerry Hatfield's photos!
