Not bad, I got a 47' with a 261, it set for close to 20 years and when I fired it up the valves never gave me any trouble. My truck's wiring was also the same. So I ripped it all out and installed new, something I would recommend. Right now I'm currently in the middle of restoration. Take a look and good luck with yours.
