I have a 73 Merc 850 and I'm wanting to replace the ignition/key switch, choke button and the tach plug. The wiring inside is corroded with some of the sheathing cracking off. I have approximately 4-5ft of extra wiring harness with good wires/sheathing that I'm going to use. But I want to replace the switches. Anybody know of any shops out there who sell older Merc parts? I called a guy here in town who said he was going to look up the parts and call me back but that was almost 2 weeks ago.
