actually the 5 speed dogleg and 4 speed box for an a series are the same size, put my two together and was quiet surprised, easiest was is 63A bellhousing and if no that do what orange is saying, there are some bolts and #OOPS# in different places and the reverse switch in a different place

its because, not all people loves dogleg. its abnormal you know :)

so now you know its a dogleg
be careful not to reverse into anything when you think you are taking off in "first" gear

Does anyone know WHY Nissan /Datsun changed from dogleg to standard pattern?

Put it in top left position and turn the input shaft and I'd the rear shaft spins in the opposite direction it's "in reverse" there for dog leg.

they made 4 speed 60a gearboxes as well so you wont be able to tell just from the size of it, they look identical to 5 speeds

Thanks it's def a 5 speed as it looks much bigger then a standard 4 speed box

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

Still could be a dOgleg but depends.

Is it cable or slave cyl activated?

It doesn't have 63a but on the front casing it's stamped 60?

put it in a car and drive it :)
