- I am sure that it is. The TRF catalog calls out a different pipe for early and late TR6s, the early being threaded for SAE, the later being metric. This corresponds with the change from 16P and 16PB

- Don't forget that you'll need the "late" TR6 caliper mounting bolts. They have an imperial thread, but a metric unthreaded diameter. IMHO, you should also consider upgrading the rear wheel cylinders

- Paul, I'm in the minority here, but IMO it isn't a good upgrade for a TR3A. It doesn't increase the swept area (which would improve resistance to fade), so all it does is reduce brake pedal effort.
