There are three diferent brake setups on these that i know of.
The first is found on cars up to about '79 or so & the brakes are the imported Japanese ones.
Next came the first of the Aussie made Girlock units, followed by the improved Girlocks. All are supposed to be good, so grab the whole strut assemblies while you can, then figure out what you can use later, then sell /trade/ or give away what you don't use.

The gear lever on the late Japanese gearbox in 200B's will fit the Bluebird five speed, which then makes one of these gearboxes a true bolt in job as the gear lever was shaped to clear everything in the car perfectly. It sure works for me.

The engine is an L20b [the L20 was a six cylinder] & the heads are supposed to be good. Hopefully someone will add to this.
