Front hub retaining castle nuts

Morning, could anyone give me information regarding what size and thread I should have on my (1951 side valve series mm low light) front hub retaining nuts. I have started stripping the brakes as the vehicle has been garaged for over 10 years by the previous owner and found one side to be a totally wrong type of nut and both are completely stripped. I keep reading conflicting information and cannot find any for sale. If anyone could point me in the direction of a supplier, I would be most grateful.
Thanks Lee

My knowledge of pre-1000 Minors is next to non-existent but have a look at this thread:

Thank you for that, it's very interesting what some clever folks do, my stub axles are in okay condition, so I just need to find the correct nuts to replace the stripped ones.
If I cannot find them, I have been told I can change the whole set up for later ones , including stub axle, trunnions, hubs and later brakes. I just have to put the original steering arm in. Does anyone know if this is correct.

I found another thread which says the nuts you need are 5/8" BSF 14 TPI

And if that is correct here is a seller:

Just for anybody reading this in future, these nuts are for Series MM and NOT for later Morris Minor 1000 cars which are 5/8" UNF
