BSA C12 rear axle

[ALISON]

Cane anybody help. I need the  rear axle wheel nuts, Part number29-6311 and 29-6217. Dragonfly can supply but they are being manufactured and has been several months now waiting. Second question can anyone tell me the spindle diameter and thread size.
Appreciate any help on these matters.
