One thing that did occur to me is that using truggy ratio diffs instead of buggy would lower the gearing a fair bit- I'd say plumb the numbers into the calculator and see what it says. In theory, the truggy ring gear & pinion is all you should need to make the change, so you can keep the rest of the UE 8spider diff (a bit of shimming perhaps, but little more)...
