In another post, someone asked what alternatives there were to the 10mm square drive found in the Drain and Fill plugs on Widetrack Sierras. Sorry I can't find that thread, but this one will do (maybe?)
All Suzuki 4wd gearbox (and Diff Drain and Sierra Transfer case) threads are the same M16 tapered thread, but various models had different "Heads" on the threads to remove them.
The LJ50 and 80 had a 14mm square drive male that was used with a 14mm spanner, Suzuki P/No 09246-16003
The early SJ410 had a 10mm Allen Key Hex, P/No 09246-16004
Late SJ410 had a 22mm Hex head with aluminium gasket (Ring spanner or socket), P/No 29446-80050
SJ50 and SJ70 had the 10mm Square drive that fill with mud and rounds off your 3/8" adapter, P/No 09246-16009, or 09246-16010 with magnet.
As the earlier numbers supercede to the later ones, the early ones may no longer be availble from Suzuki, so contact your Suzuki Stealership to confirm, Oops I meant Dealership.
