Thanks for all the replies. Not looking for concours level necessarily at this point, but would like to replace some wires with period correct stuff if possible. The wires going to the coil seem like they are about to break, the rest look good, just the sheathing getting a little frayed. Down the road we will strip the truck down to the frame for a proper restore, at this point we’re just looking to make it safe and reliable. All wiring actually looks pretty good overall, I highly doubt it’s original but looks the part.
