All 86-95 USA/canada SWB samurais came with 3.727 gears. I believe the LWB samurais came with 3.92s. You should be able to use trackick gears in your LWB, since it uses the same axles as a SWB, doesn't it? The trackick ratios available are.....4.30, 4.62, 5.12, 5.38 and 5.62.....with 4.62 and 5.12 being the most common.
