I found a couple of small bearings in Mercury packaging. So far by going through the books I have I can not ID them. Part number on the packages is AJ-33770-A. Does anyone have a book that has this part number listed somewhere? I am curious as to what year these fit and where on the car they are used. Thanks Rod

Don't know where it goes but all info says '56-'57 Mercury.

Thanks, will ask on the late V8 forum. Packaging looked earlier than 56-57. Rod

If it is in fact Lincoln Mercury, The numbers that high in the FoMoCo system are body related. 32000 to 33000 would usually in the rear quarters or the trunk some where.

The "AJ" prefix - I think - denotes multi-application, and isn't brand specific. I've seen it before and I think that's usually the case. And the 5 digit base number would indicate a body base part number, vice steering components. But for reasons unknown to me, and which was done before I worked parts departments, Ford used the 3**** format for some steering components, as they also used 7**** formatted numbers for transmissions.

Best I could find on that number is as stated previously, that it is used on 56-57 Mercs.

The fact that it is in seemingly earlier packaging is insignificant; I remember seeing the old red/flesh color packing with Edsel still on it in the early 70s - and the parts came from the depot. Maybe that's where the term "NOS" originated?
