By then end of next week, they'll be crankshaft sensor brackets and discs available that can be fitted to the original bottom pulley with no need for welding, machining or messing around with different alternator pulleys etc!

As for removing the old bits of your loom, the easy way is to disconnect the battery. remove all the tape from your loom, chop the two plugs off that go to your ecu's then just remove those wires one by one, you'll end up with just the bits that you still need! re tape it then add the cossie loom! Job done with no crap thats not needed in the engine bay!
