Part numbers between the ST205 rear hub carrier and the the earlier cars (ST165/ST185/SV25) are different, but you can probably use one (or maybe a pair) after swapping out your hubs into the carriers. The wheel bearings are the same for all of those hubs (ST165/ST185/ST205/SV25). I used my stock Camry Alltrac rear hubs when I did the swap to the rest of the ST205 suspension parts (subframe, diff, arms, axles, brakes) and it worked out fine. I am keeping the ST205 hub/knuckle assemblies as spares for later though...
