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. Has anybody installed one of these units yet. If so 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 around to see if anybody had any info or can direct me to someone who has.
