I have a big block toploader with 1-3/8" input, long tailshaft and the tag on the case is
RUG-AU
PILOT
That makes it, if I 'am correct ,a 1970 fairlane/torino 429cu,
So there is no serial number on the tag, just capital letters PILOT directly under the rug-au.

I have been told it's just a designation of where it's made, plant etc.
But everything I have seen has a serial #
Any ideas?
