Think so Chris, I was multi tasking @ the time!. Are the 164/156/166 similar?? Gerry mentioned that since the Beta parts are now thin on the ground the changes incorporate Alfa parts. From memory, they use the Alfa larger bearings and Alfa front hubs; Alfa CV's inners / outers. Useful as you can use more of the donor parts when building from new. Just need to sort shafts!!
