Dana 44, Steering Arm Kit, Right Side, 1", 4th Hole with Studs, Nuts and Cones, (PM6313-008R4) esr3694275 most people use a blockD44 cross over (passenger's side), 1" tall. This steering arm is 1" thick, and has 4 holes for HD knuckles. The 4th hole is designed to be used with knuckles that have the 4th hole. If your knuckle has 3 holes, get the steering arm with 3 holes (search PM008R). There's no reason to have a HOLE in your steering arm unless there's a stud to go in there! Works great in cross over applications on Jeeps. If you've got a GM Chevy, the PM1011R is your best
