Question about closed lug [center cap]Alpinas???

[sfdon]

After two years of hunting for a set of the locking wheel caps for my Alpinas, I finally found a set of four in England for a mere 133 pounds sterling.
The problem is they just don't go on! Do I need to change to studs instead of nuts?? Or do I need to get lug nuts without the chrome cap??
Any suggestions would be appreciated!
Thanks!
Don

ps.- here is a pic of the caps:

Generally, wheels with caps require open lugs. You can find suitable ones (12mm x 1.50 thread) at almost any auto parts store. I was in an Auto Zone a couple weeks ago looking for some valve stem caps and noticed they have them.

Thanks Tony... Sounds easier than changing hubs or

pulling 20 studs for shorter ones.

Do these caps fit on both the original and repro (W&N) alpina rims?

James- I have no idea!

I know the lug hole is a different diameter, but i suppose the diameter where the cap fits will be the same. How do they lock to the rim?

There are flanges that get positioned first and then the key turns a metal tab to lock in the last side.
