After fitting a Dolomite rear axle in my car, I need 8 7/16 unf open wheel nuts to bolt on my pcd adapters.
I don't care what they look like as long as the thread is good, as they won't be seen.

Thanks
Tony

Haven't got any but classic Mini wheel nuts are 7/16" UNF and probably have the same angle seat if thats any help

Nope, classic mini 3/8unf

Pre 72 ford and other old stuff should do the trick, even TR's and tr saloons.
Or how about these
TRAILER PARTS WHEEL RIM HUB NUTS 7/16' PACK OF 4 | eBay
though not really that cheap....

Sorry , yes they are 3/8".

..........and they look tiny!

Rimmer bros and get reamed by the prices asked for those :-)
