If the coil pack is a 1st gen one , HT leads can be got from triggerwheels. If its not, I don't know! The problem with buying from halfords is that they can only search for make/model of car, on my car the coil pack is a lot further from the engine that it would be normally.
You will be able to get spacers for the trigger wheel at triggerwheels.com
