Spent a productive couple of hours in the workshop last night.
Fixed the thread in the AJP caliper (problem was the Banjo I had was a M10 x 1.25 but the AJP uses a M10 x 1.0mm thread). Using the correct tap cleaned thing up nicely.
Now I need to suss out brake line length and order/make them up
Also finished the numberboard, probably get it powdercoated.
Tidied up the welds on the brake pedal. That needs to go off for powder as well.
