Nelly`s right Jools,the threads are the same.I`d personally do it the way Jasper has,direct into the caliper,it looks cleaner and is in keeping with the "era"
All you do is swap the bleed nipple around,I`d defo run twin lines, looks cooler and more symetrical.
I quite like the blue anodised fittings(like Natty`s and as per race bikes of the time)but if not the black like Jasper`s if you`re not confident enough to we bright colours
You will find the billets work really well Bendix pads from Nelly and cast iron floaters
