I recall breaking the head of one of these screws on the rear strut last time I replaced the strut housing and it's due time to replace that strut again, but I was not able to get the remainder of the old bolt out. Does anyone know a part number of size/pitch for this bolt so I can order a new one to use with the new strut? The one on the other side is not wanting to budge and I don't want to snap that one as well. Already tried heat and PB Blaster overnight but it seems to be rusted on fairly intently. Last time I did this, I just welded the sensor onto the strut body with a tack, but I'd like to not do that again obviously!
