I’ve never heard of “set”, is that a reference # that one can order by? I’ve always used the p/n. 
Thanks

Yes, SET6 is a part number.  It's all in the spreadsheet URL I posted a few messages back:

front: SET2 (outer, small) SET6 (inner, large). SET6 is LM67048 (bearing) + LM67010 (race).

and

AMC15 axle: BR6 is SET6 is ( LM67048 + LM67010 ) is AMC/Rambler front hub AND AMC/Rambler rear axle bearing.

YOu should be replacing them as a set, if you need to replace them. I wash mine in a mix of solvent plus motor oil, shake 'em till all the griet and grease is out, and examine carefully. Nearly all of the really old bearings that were decently lubricated, I found, remain usable. WHen I see discoloration or grooving, I replace them. New parts quality is highly variable and the older Timken and other brands rarely suffered from poor quality, just wear and (lack of) maintenance.

Never knew bearings were packaged and identified as a “Set-“, learn something everyday! Found the AMC Set2 and Set 6 is same as 1967-1978 Camaro. Makes this an easy job. I will post all results once I have parts on car. 
Thanks again for the help!

Almost all front wheel hubs and bearings are the same, drum or disc brakes, as far as bearings and actual spindle dimensions (the part the bearings ride on) are concerned. The lone exception is that 1975-78 used a different, larger bearing set. This corresponds to the Big Bendix (3.1" piston caliper) for all 75-76 models and 75-78 big cars. For some reason AMC kept the big bearings on the 77-78 small cars but the caliper changed to a 2.6" piston.

The other difference in spindles is the base thickness. The bolt pattern is the same from at least 1952 (1950 Nash Rambler... not sure about the big Nash cars before 52). The base thickness varies depending on width of drum and type of brakes. Disc brake bases are thicker than drums (except the early four piston Bendix discs), wider drums a little thicker than narrow drums. Easy enough to swap them -- use spacers (grade 8 washers are hard and will work) to center the caliper. A bit harder with drums as you can't see as clearly what's going on, but the base of a disc spindle can be milled down if necessary.
