what is the length and width of the holes in a divided T4 flange?
 

I am trying to determine the size of the two holes rather than the bolt pattern. I already searched, which was a pita because 't4' is only two characters.

Going from an old rotomaster print..
The bolt hole pattern is 2.75x3.25
the bolt holes are 3 @ .406" diam
1(upper left) @.440" diam

The gas passage holes themselves are 1.98"x1.36"
the divider wall in between them is .22"

The overall flange size (outside) is 3.75"x4.25"

That's what I was looking for. Thanks Max.

Thanks, I was also wondering this.
