Upper Vent Tube for PCV pipe

[steptoe]

I have a 1964 Monza which has the old draft tube breather system. I am converting to a factory PCV system but my upper shroud (engine cover) does not have the hole to put the vent pipe through. Would anyone know how to measure where to cut a hole through the shroud? It has to be exact because the pipe is metal and will not bend. I do not wish to mess up by making a hole much to large for the pipe. Thanks in advance, David

Well, I guess I'm lucky because I measured in 2 crossing directions after looking at about 10 pics of PCV holes and got it exactly perfect. Now to finish the installation.
