i have a question or concern about my x-over. i just installed it on my k5 and have a small issue. on the passenger side steering arm, the directions say to use the forward most hole in the arm if not doing the high steer kit. well i cant get the castle nut down far enough to get the cotter pin through the hole in the balljoint. as it is now i cant even get the smallest cotter pin in cuz there isnt enugh of the hole showing. any suggestions?
