im gonna do my shackle install this weekend,,,i've been soaking them every day with wd40 and i tried to break them loose yesterday,,,,3 of the four turned eventually,,,but of course theres always one,,,,,,i was wondering if anyone had a pic of what the inside of the subframe rail looks like in regards to the shackle nut thats welded in there,,,,basically, how far down and can u get a wrench/homemade tool down there if it busts(not wanted to cut open the rail). requesting the pick as if the bolt/nut breaks,,,i've got to remove my hidden hitch also:gonnablow
