They can but it's worth taking them apart to check for rust pitting first. To do this, I put the bearing in the palm of my hand and tap the thrust side smartly with a copper hammer to force it apart. You can then inspect the tracks with a loupe to check for rust pits, also the balls, which can be renewed for little cost. When you are satisfied, the bearing can be tapped back together again.
Any rust pits, discard the bearing. I ran one years ago with a few small pits, after 5000 miles, the bearing tracks were completely gone.
Unfortunately knocking angular contact bearings apart can indent the balls causing later problems.
Using unmatched balls defeats the purpose of the original set of carefully matched balls.

I would have thought that a matched pair of Austin 7 SKF AMS 9 or RHP MJT 1 1/8 angular contact bearings (imperial size) would be very difficult to find.
Especially the later narrow outer ring pair.
Where do you get these ?
