Didnt change til 55.
If you have the reg. off,it will be stamped either in black ink or into the case somewhere on the regulator. Look around the outer flanges. | | | | | Joined: May 2006 Posts: 92 Shop Shark | | Shop Shark Joined: May 2006 Posts: 92 | Arent they stamped with date codes? How do I decipher it? What happened was I bought a bunch of used parts that were for a 54 chevy Bel Air that the guy already sold. I looked today and both of the generators I got say 12v on them....I thought the 54 was 6v also. | | |
