23mm MC plumbing question Options

[Qarl]

I will be installing a 23mm MC to feed the bigger brakes on the new car. I have heard that their are plumbing issues, and clearance issues when installing the bigger MC.

I'm looking for feedback from those that have done this.

Here is a comparison of the new and old MC. I have some questions.

1) Ports 3 and 4 are the front and rear output ports. These correspond (location-wise) to ports 1 and two on the new MC. It seems that I can just transfer the hardware and lines over without any issues. Correct?

2) The locations of the feed lines are different between new and old. Is this going to be a clearance issue?

3) The hydraulic pressure switch (located between ports 3 and 4) does not have a corresponding location on the NEW MC. But there is another output port on the bottom of the MC (underneath port 1) that I can use? Any clearance issus here?

4) Does anyone know what the bolt on the top of the NEW MC is for? (between the red caps)... If I remove it, will a genie come out and grant me 3 wishes?

These would be easier to answer if my car body were in the same location as my parts. (hopefully in a couple of weeks!)

Thanks!
