Right maybe someone can help I went to get a new set of HT leads for my disco 2 4.0 V8 on LPG on a 2000 when I got them home I found they were the wrong ones so took them back only to be told there was only one set for my car listed I tried to explain with one of my leads in my hand there can't be. The leads I was given had a plastic part sticking out where it goes into the coil pack but the ones I have on mine are flush with the rubber and have a white ring on I've had to buy a set online but can anyone tell me why every shop I went in I got looked at as if I was mad.
