I had gotten 2 pairs of 94/95 spindles a few weeks ago from the junk yard. I went again today and got another pair of spindles off a 94 Mustang, only these ones are different. They have some kind of electrical connector coming off them and a sensor by the hub and the hubs have some sort of 'splines' or something on them. I ran the part numbers, so I know for sure that all 3 pairs that I have are all 94/95 spindles. So is there any difference?
