Here is another head scratcher. Taking apart my 1969 to have a major resto of body with paint. It is a 12B(1968)build car. I have owned this car for over 33 years and as far as I know there is no evidence it has ever been apart. I have it pretty stripped down with everything removed from cowl,dash and interior.Just a bare shell now. I noticed upon removal of the speedo cap plug that it has a chrysler product insignia embossed in the interior side.can't post pic,but it is clearly a Chrysler part with CDPD(Chrysler,Dodge DEsoto,Plymouth) insignia. I am searching if other 12B owners would chime in if they have the same or anyone for that matter. Could there have been a shortage and this was provided from the vendor? I have no reason to bekieve this was replaced and the car is original in most all respects. it is a real muncie car with born with trans. Look forward if this can be confirmed in other cars. thanks.
