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!

I saw a car today, a converted 73, that had a booster assembly bolted to the trunk floor. It took up about 2/3 of the left half of the floor. I wish now I had taken a picture. I'm told it is quite effective. Don't know that it is necessary though.

I think that rebuilding my 20mm will be sufficient for several years. I'll have to try to find some more kits.
Note that the odd metric sizes are due to the fact that the true sizes are in 1/16 of an inch increments.

17.46 = 11/16
19.05 = 3/4
20.64 = 13/16
23.81 = 15/16
