Default NOS Ford Autolite C3TZ-10505-B?

Any Ford guys out there? ...Was hoping to post this in the &quot;classified&quot; section but ran into a weird situation. Today I opened this NOS box holding an original Autolite regulator and discovered the part number on the box doesn't match the part number on the regulator.....[img]<<GRAEMLIN_URL>>/no.gif[/img] Part number on the box reads C3TZ-10505-B but the part number on the top of the regulator reads C2AF-10505-A. Now my question is...Is there a similarity between these two regulators or is there a difference??? Can't understand why two different part numbers could be on one item! Once I find out why this is the case I will be posting it for sale. Pics below......Any help would be great!

Thanks,
Sal [img]<<GRAEMLIN_URL>>/dunno.gif[/img]

Sal, I used to work for ford motor company. They would supersede part numbers all thi time. 10505 is the basic part number for a regulator. C is 1960, 2 would be 62, A is full size ford. Although with electrical parts that isn't the case. I would say it is just the next years voltage regulator. They both state the same 15 volt and 30amps. There was a book that we used called OSI, obsolete, supersede, interchange. Maybe one of the ford gurus on here has one and can check.

Thanks for the info Buddy. I'm not a Ford guy but would you know what some of the full size Fords these regulators would have been on? Any positive feedback would be great so I can move on with the correct application on this. Thanks again.

Most parts would be released to/by one carline and then used on multiple carlines. So full-size might be the first and the part # would show full-size. But truck and Mustang could also use it - part # wouldn't change.
You need a parts manual or application chart. I actually used to release regulators &amp; alternators, but I don't have that old info. [img]<<GRAEMLIN_URL>>/smile.gif[/img]
