Hi Stu,
I have plenty of mountings- The rubber donuts and aluminium platforms? I have the rear hub nuts as well, at least 1 of the 4 slot type and plenty of the more robust multi slot type. I am having a clear out tomorrow so I will see what else I turn up. Let me know if any of the above are of interest.
Yes, they will all be of interest! If the multi-slot hub nuts are more robust and are the same size / threads, then I think it will probably be better to go for this type rather than the 4-slot. The car currently has the 4-slot nuts which is why they were requested.
