The nut has internal hexagon Sam, not external as in a "normal" nut. I use a piece of 40 x 40 x 5 box and just round the corners off a little until it's a tight fit INSIDE the nut. It's more of a locking ring than nut. 40 x 40 box and big stillsons, job done.
And talking of diffs, who's a lucky boy ? Rummaging in a box of parts I bought for next to nothing and came across an as new ring gear under an old wiring loom. Moved some more bits and found a diff case, turned it over and it has a pinion in it in the same condition. So, a bearing kit and I have another as new 300 diff :rating10: :yeahbaby01:
