I removed a 3rd member with a Detroit locker from the rear of my 90 V6 SR5 that has a bad set of 571 gears. I purchased from All Pro Offroad a new 3rd member with Detroit locker and 529 gears. I want to use the old 3rd member up front with a new set of reverse cut 529's. Will it fit in the IFS ok? Thanks for your help, Robert.
