you can still find some good stock ones in good shape. i wouldn't personally try to fix something that has a bunch of splices with electric tape. you can seperate it and just replace the part you need like the starting circut, charging circut, main thru firewall section, under dash section. yes i agree electrical fires are bad and if you want to change every wire that's fine but most trucks from the 60's prob don't need every wire replaced. heck a rock from the sky could crush it with the new wiring, then you'd be out all that money! unless you got rock insurance.
