Detroit ez locker is installed in a front IFS housing that was in my 87 4Runner with 4:10 gears. There are 4 pins with springs that keep the locker engaged. One pin was broken when the center pin broke. My brother then installed in his 91 pickup with only 3 pins and had no problem turning 37, hooked up great. If needed you can install shims behind the remaining 3 springs to hold it tighter but I thought it worked great. $100. No shipping at this time. Pics avable this weekend. (Rear axle was sold)
