Pro-parts is always very cheap
Yeah I have been in contact with the ebay member, will they def fit do you know and is the quality good?
nah leads and plugs are very simple job, even a 17 year old can do them
change the leads one for one. then you cant loose the order. there should be a little orange clip on one of the plugs to help pull them out. but if not there not that hard to get out. as for the plugs you just need the right socket 17mm i thing and an extention bar as there deep down in the holes. unscrew them out making sure nothing goes down te holes. then tightern the new ones up. not to tight or you may strip the threads
