4 speed gearbox refill plug size
Dumb question Wednesday, but does anyone know offhand what your meant to use to undo the gearbox drain plug with?
I have changed the gear oil as per the other gearbox thread, but upon refitting it have lost a bit through the tailshaft seal.
With the manual bodyshell, there's buggerall room around the plug, can't even fit an alley key in.
I know it's a square head, and should be metric, tried a bolt head but no luck, and bigger than 10mm?
fun and games.
