I have one that has maybe 3 hours on it...my new PlanePower Alt. came with a new one so mine is just sitting around waiting to go on ebay...I can make you a good deal on it...PM me for pics if interested...thanks and good luck!
I found a shiny new one from the local NAPA "aviation" parts dealer. The regulator used in my 1971 plane is the exact same (even the plug) as used in most Ford pickup trucks up to the 80s and maybe even the 90s.
