Thanks Jeff, I think I will be crosseyed the rest of the day. I spent 25 minutes looking at the list and did not find the number. going to get some construction paper to put over the parts of the monitor other than the parts number. I did not find any AJ prefixed yet, but did see some BAJ prefixes and the closest main body number I seen was 33667 which was for the horn button. I will spend more time at this later today. Rod
Rod, it's not a body number; if so it is incomplete and I don't know of any item that Ford ever printed partial Part #s on their boxes or packages. (QUESTION - Is it a for-sure genuine F-L-M package?) ie. - if it were a body base number, the part number would incorporate the body style for which the part was originally developed.
Example: if it was for a 2door hardtop, body style 65, the Part # might be AJ-
6533770-A. If a convertible body 76, it would b AJ-
7633770-A. As I think I mentioned earlier it is very likely a steering related item. Chassis numbers - those below 19999 - do not use the body #prefix.
Body #s start a 0xxxx, which is
generally cowl or front vent related. But some exceptions and 33770 is very likely one of them. fun stuff, eh?
I sold Ford parts for years and wouldn't begin to think I knew it all back then - or that I do now. It used to be like a second language back when we didn't have computers.
Base # in the book is probably listed as 3-3770 (in the steering section) but I don't have a 50s Mercury parts book to verify it.
re: that parts list? You might try copying and merging it into an Excel spreadsheet, then you can sort it by prefix to make looking for that number a bit easier. Hope this helps. Ron
