Looking for 1/0 Copper Lugs

I ordered a set of 10 from Sky High but they were oversized and didn't fit my 2/0 Welding Cable. So where can I get some of these badboys?

Really? Because my 2/0 Welding Cable is very small compared to the Sky High Lugs... Like a nickels width gap. I was told Skyhigh uses oversized wire/lugs. My Knukonceptz 1/0 is the same size as my 2/0 welding cable and is also too small for the sky high lugs.
This is my welding cable and its quite small compared to my 1/0 sky high lugs:

So I don't know whats going on here... All I know is I bought 20ft of 2/0 welding cable and its too small for the $20 in lugs I just bought... some are saying sky high is oversized some are saying its not, all I can say is theres a nice gap between the wire and the lug and its the same way for my 0/1 knukonceptz.
