Thanks, RL331. I did look at that, and it did not at all conform to my 56mm inside measurement and 62mm outside measurement. I assume it must mean a cap which fits entirely over the lug bolts as well. But, this is the problem I spoke of; various references provide various measurements, without saying what is being measured. Thanks, Marco

Maybe 70mm is incorrect, I thought I took hat measurement off mine - but it doesn't matter, the part number is correct without a doubt because I looked that up myself.
