Toyota 10.5" ring gear...
As far as the "NEW" rear size by the Toyta company, I don't know what gearing is in there or anything about aftermarket gears, but they'll come soon enuff. The smaller Banjo type Toyota rear has alot of ratios from Richmond.
IF you could pick up a junk one, the swap into anything could be cheap since it is an import and not a commonly sought after rear.
