So the answer is: check the label!

What the hell is the difference between 2 pins and 4 pins anyway? What are these pins, where are they, and what do they do?

just the strength of diff gears and case 2 pin is actually one shaft holding the 2 diff planet gears ,4 pin has 2 shafts or a cross shaped shaft holding 4 diff planet gears, diff carrier is also a lot stronger

Sincere thanks to everyone who replied to this.
I'm going to pit a 4 pin diff on the front now.
Chequebook out!
Cheers.

Make sure it is a front diff you can't stick a rear one in the front.

Oh Boy, what next? 
So, I have to be very careful how I place the order with Ashcroft; if I ask for two 4 pin diffs, I might get two rear ones?
If I ask for one front and on rear, I will get a 4 and a 2 pin!
I'll think on ....

rears do fit in the front its the crown wheel and pinions that are handed, though if you fit a rear cw/p in front it runs on rear of teeth like disco or defender

Right, if I understand, the diffs are interchangeable physically, but the crown wheel and pinions run differently?
What does this mean? Is this a bad thing?
Cheers.

up until p38 lr used the same cw/p front and back ,the one in the front driving on the rear of the teeth ,whether thats an issue depends on usage similar with 4 pin, though a high mileage cw/p isnt going to like running on opposite side of teeth

obviously you are best getting the correct ones if you can ,but it is possible to run rears in front

Can you not just order the 36L or whatever label is on yours?
