Yes guys, the wheel bearing situation can be a bit confusing. My Beta still had all of it's original bearings, bar one, in the original SKF Italy part. The numbers were still legible, so I just emailed a few bearing stockists here in Perth, and found them to come as a kit (with a washer and dust seal, not applicable for a Beta, but apparently suitable for a Ford 9" diff!) for a bout AUD$50.00 per kit.
Front and rears are the same on my Second Series, Pre-facelifted, brown-dash-with-oblong-headlamps Coupe.
They are a decent Japan brand, but cheaper thank the SKF or FAG part, though I'm assured just as good.
The retaining rings are different front and rear, but are readily and cheaply available from Midwest Bayless in the U.S., or Ebay if you get lucky.
Midwest Bayless also sell a nifty tool for turning the retaining nut in the hub, but if they're are anything like mine, you will need a big hammer and chisel to get them moving!
The tool is very handy for fitting the new ones though.
Hope this helps.
