Rose joint size

[Wulfgar_SDL]

Yet another trike question.

What size rose joints would be suitable for this type of swingarm set up?
See pic attached.

I have been offered the following sizes.

5/16 BORE X 5/16 THREAD
5/16 BORE X 3/8 THREAD
3/8 BORE X 3/8 THREAD
3/8 BORE X 7/16 THREAD
8mm BORE X 8mm (1.25mm PITCH) THREAD
10mm BORE X 10mm (1.5mm PITCH) THREAD
12mm BORE X 12mm (1.75mm PITCH) THREAD

on my new vw frames i'm using some 5/8" ones i have leftover.
i'm no bike engined trike expert but i'd say you need larger bore theres a lot of constant strain on the bolts.
