    +1 for the trutrac. the valutrac is not offered for 28spline axles only 30spline. build it right or dont do anything. being cheap will have you spending more later. the 8.5 will take some abuse if set up corectly.
    1982 c10 lsx swaped, NP tuned, true duals, 4:11s, trutrac, e-fans, CAI

    Well sounds like the best way is to build it with the trutrac, sounds about right about spending more the easy way out.
