When I bought my '64 galaxie I called up Donahue to get all the parts books, manuals etc that I'd need. he sold me a '64 parts book, shop manual & a couple of other things. I ask him if there's anything else he can think of that I'd be needing. He
answers *no*

That brings me to now, I spent an hour last night trying to find the damn wheel bearing #'s in the manual & discover they ain't there. Today I call Donahue & get told that because the rear brakes are the same as a '63 the part #'s would be in the '63 parts book. Well thanks for telling me that when I was ordering books ...ARRGGHH!...
20 minutes ago I pull the tag off the Diff to find out what I have got back there. Guess what? thats not bloody listed either. So far this '64 parts book is about as much frigging use as a chocolate radiator.

So what the hell is:
WBS-BN2
3.00 3KE 105

I can figure out that 3.00 is the ratio & WBS is the model, BN2 is the model suffice, 3KE is the date & 105 is the plant code, but have no way to decode it. WTF have I got here?
