flushmount oil cap???

Does anyone make an oil cap that uses an allen key or whatever to take it off/put it back on? Mine is going to hit the hood and I think a flush mount would keep it under the hood!

no1lower on here i think recessed the whole cap, threads, and neck flush with the valve cover. it looked like a lot of work, but looked very nice and clean when he was done. not sure where that thread is but im sure someone on here knows where it could be found.

I just need a plug, I'm not trying to modify the valve cover. I figured LC had a flush mount plug but they don't.

I just had a freind mill down the top of the plastic one and then one it was gone filled the top of it in with mighty putty and while it was drying put a allen head on the top pushed down to make the whole and then painted it....it was all black but it worked then I swapped out to a differnt valve cover and got the low pro lc one and that worked fine too
