The steering knuckle nut I've found at Classic Industries, as well as a few other bolts and I'll try again with the rear studs and see what I get sent. I'm intending on replacing all of the original bolts even though they seem in good condition... I've contacted both Fastenal and Forest regarding UK shipping, so fingers crossed.
Hopefully that's all my problems sorted thus far, cheers
