If you're talking about 30/40 lugs, I replaced all the beavertails on my Radio King as one of them stripped out while I was playing! The repros I got off eBay actually are very close to the real thing. They may be the slightest bit smaller (as in, you'd need them side by side to tell) and the mounting screws are metric and I had to order them special. Other than that, no complaints. The feel plenty sturdy and look great.
