Hi, I am missing one of these of the rear of my Busa cylinder head, either I get one to blank off or someone can tell me what thread it is so I can get a suitable bolt...I'm guessing M10 fine?

If anyone has one spare I would be happy to trade ...

I think you will find that the thread is NPT as its a taper thread.

I could probably get one for you as I nicked mine out of a old engine from work but I am off on me hols in the morning.

I would check on the Think Automotive website as they will be able to supply a blank for you if you need it quick

If its a 1/4 NPT then I have a few brass ones around that I can try.... thanks, will give it a go and see.

Enjoy your hols
