Hi everyone I have a 2H with a Safari turbo kit in a 60 series. I'm looking at putting a EGT gauge in. I am trying to work out the best place to put in the probe in. On the exhaust manifold there are 3 raised areas with thread (see pics) Can these be used to drill out and put a prob in? There is one in the center and two further up. Sorry about the superficial crack in there too haha. Cheers!
