If anyone would like to add something I can alter and repost then we can get a decent pier design by committee.... it'll probably look like Simpson's Car.

Yep, that is much better.
I would avoid the rat box all together if possible though,
if not, I would make the bolts as short as possible (there should be no more than a couple of mm of thread visible between the nuts) and use something like 5/8" or 16mm bolts if you can.
fwiw) 1 degree of Az adjustment requires 3mm of clearance in a rat box with a pcd of 200mm
