National is a Federal-Mogul company/brand. I only know because I googled it last night:
http://www.fmmotorparts.com/fmstore...oTransOilPumpSeal#.VtT7g3v4kco|horizontalTab1 Now who owns Federal-Mogul, I can't tell you. I have made aquaintances two guys who work for F-M and one who works for Timken. One guy at F-M makes engine valves, don't know what the other does and the guy who works for Timken identified his company as doing bearings. I guess he makes bearing.
No local place to get the SKF, I checked. But I have a friend at one of the local autoparts companies that can order me the National.
If I told you I am afraid of ordering just anywhere because I don't want a fake/poor quality seal, would you believe me?
