If it has "60" cast into it
it could be
4speed
5 speed std patern
5 speed dogleg pattern

IF its a 5 speed dogleg, the drain plug will point to the REAR, not downward as is the case for the std pattern 5 speed

or simply put it in gear in the TOP LEFT position and then turn the input shaft. If the output shaft turns the OPPOSITE direction, its a dogleg 5 speed (FS5W60L) ie you are in reverse in the top left position

to easily see the output shaft rotation direction, push on a short piece of 19mm poly retic pipe or a plastic water bottle onto the output shaft
