Pete,
My 4.56 used Diff arrived today, and if all goes well I will drive it Tuesday. Tacoma Speedo will make me any ratio change...they just need indicated speed vs GPS speed. Thanks for your reply.

I am getting ready to do the same on my 92 Warrior 21RB. Can you stay in 4th/OD in the flats at 55mph? (GPS or Speedo corrected)
With my 4.11 any wind or slight grade and it downshifts. Tim
