Technical Which way around?

It's so simple, (if you are fluent in Italian and algebraic equations.)

She’s young enough to be my daughter, so I’m ashamed to admit I think I’m in love
I might have a chance of understanding some of this if she didn’t talk at Mach 3

Cinque I feel for you - I'm just soooooo glad that when I completed this task it went together exactly as Haynes said and yes I did have a monumental headache after, but nothing a large glass of red cannot cure. Good luck.

T’was a bit early at the time but I’m currently enjoying a gorgeous Primitivo, Tesco finest no less , whilst watching the Champions league
But I digress, I made a bit of progress this afternoon as my shims arrived early
After several attempts I got the pinion teeth central on the crownwheel. My estimation was off and it was too far out so had to keep taking a shim out at a time but hopefully worth the patience. Although I note P.Peter on a previous post mentions hypoid diffs aren’t necessarily set up centrally.
Also in other news I’ve got the lash within the Haynes range too. I’m not fooling myself that I’m there as I’ve got to do the dye thing and check the contact patch but I’m happy with this as a starting position.

I made some progress today. In the end one by one I had to put back the pinion shims as the contact pattern wasn’t into the root enough, so ended up back to my original calculation which is kind of amusing. I got the lash at 0.1mm so good as well. I haven’t done the thing with the rod and a 1 kg weight, still to do. However I was stopped in me tracks as when I tried to select gears I found I’ve got the same issue on that faithful day at Brooklands when the box locked. I’m gonna start a new thread on that, I won’t witter about it here

Nothing to do with those interlock slugs that fit in gear change rods? Not the three balls behind the plate with springs.

I know from my description it sounds like a very likely cause but I’ve done those two little kind of oval ballbearings and the pin in between a few times over the years so I’m pretty familiar with those strange parts.
Thinking I may perhaps have a bent fork I also looked at overriding the selectors by removing the 8mm bolts to manually (albeit perhaps moving things out of sync) try and find a neutral in there somewhere but I can’t no matter what I try.

Is it possible as box was tightened it preloaded something?
You haven't left the dial gauge in there after the bottle of Italian red?

How does it work with selection of fifth gear? How is that prevented from being simultaneous with the other gears.

Without looking at the lay out I suspect in all the other gears when in use, the one that transmits drive to the fifth gear "freewheels".
Can you try rocking the gears when it locks up and see which one is "solid" with no movement at all?
