Here’s a CJ-3A that still has the 6 volt system. This might be a good find if you want to restore a CJ-3A without too much work.
“This is a very nice original jeep. (very rare). Most have been modified heavily. The only thing modified are seat belts, roll bar, lockout front hubs, and of course wheels and tires. The original engine, transmission and transfer case are still under the hood! It is still 6 volt with a new battery. I had the clutch replaced a few months ago and the mechanic didn’t do it right so I haven’t driven it since then. I knew I should have done it myself!!! It wasn’t aligned properly so it has a vibration. I haven’t had the time to fix it myself and I don’t trust anyone to do it for me. It needs a new accelerator pedal linkage and he’s ready for all of the fun you can handle … Anyway thanks for shopping by and you can call or text me at my cell# 214-616-9911 (yes I do live in OKC, just haven’t changed my cell phone). I just don’t have the time to keep Willy up and would like to see him get a new good home.”
