Could someone please tell me the size and theads on the stock 2001 E320 wheel lugs? Are the threads 14x1.5 or 12x1.5? And what is the shank length? I have a 2001 that I'm trying to put 2004 wheels on and the the lugs are too long and hitting, I need to know which ones I have so I know which size to buy - just a little shorter.

Thanks,
