Does Lexetreme have or make a new speed "O" gear for tire size changes or rather gear size changes?
If you install it in an 89-95 truck or 4runner the electronic speedo gear from a 92-95 4cyl truck works fine. If you use an 84-88 you can actually integrate an SC400 gauge cluster into the housing of the dash, then use the same 92-95 gear on the t-case.
