What the above said. All taper bearing kits I have bought until this point have come with the bearing cups as well as the taper bearings themselves.
Now here is an interesting question (and a potential hijack!). Do the Escort bearing require pressing in or simply changing like most other taper bearings (i.e with sockets etc.)? I ask as there was a debate not too long ago where certain folk thought that the MkIII/IVs were a press in job only. I initially disagree but OTOH 200NM is alot of torque for a taper bearing which generally require a very slight (well, generally barely any preload) to last any length of time.
