Default Exhaust Manifold Flange Dimensions

Does anyone have the dimensions of the exhaust manifold flanges? I don't have any gaskets or anything to measure myself and I don't want to take my exhaust apart until I have something to replace them with.

If someone could post a sketch or something with the important dimensions on it that would be great.
I have a drawing for the 1995 - early 1996 oval style collector flanges if anyone needs that for something.
Thanks!

I have access to a 2D laser, so if I can get the dimensions I can make the flanges and the gaskets. That's why I have the secondary pipe flange drawn up already I made an exhaust system a little while back. I am not happy with it so I am going to re-do the whole thing sans-heat exchangers and with long(er) tube equal length headers. That's the plan anyways... the wife isn't happy about me playing with the exhaust again though...
I am supposed to get some dyno time in the Fall so I would like to have a couple of different designs to try out.

My 911 gaskets are metal with crush zones, IIRC. I think they're the same size/shape. I'll look around my garage tomorrow, as I may have a set.
