Where can i get a socket to remove the pinion nut on a cosworth 2wd rear diff?

This is what i need to get off, so it will have to be a deep socket


I forgot to measure the size but looking at the pic its a 12 point type but will double check tomorrow

Thanks
Marc

Tried a local Snap on dealer?

 

it is now 205-175 , ask your local Ford dealer , they might have one that they do not need anymore
