The ELockers for the GM 9.25 IFS are being used in the front axles of our trucks with some minor mods. I have one in hand and was looking for some info. I did a search and I see a few of you have installed this carrier. What did you do for the electromagnet anti-rotation? Did you fab a bracket or grind/machine a groove in the bearing cap as some have been rumored to have done? I have not had the cover off yet to check out the possibilities but thought I would ask first. I was also told some clearance grinding needed to be done. How much and where? I'm sure it will be obvious but just wanted to ask in advance.
