Keihen CV34 Issues and Question

I managed to find another set of Keihin's at a farm nearby. My original understanding was all four carburetor bodies were identical and I could use any of them to replace the one I ruined. Upon a closer look of the new rack I am thinking I was incorrect. Can someone confirm that the carburetor body from the same position on the rack must be used to replace a carburetor body on a different rack?
Another question is that I am having a great deal of trouble getting the screws out that hold the rails to the carburetor bodies. Does anyone have any tips other than heat? I have seen suggestions of using ATF and acetone mixed equally. I live in an apartment and would like to minimize the amount of chemical mixing I have to do due to lack of space.
Finally, I have noticed stripped/seized idol mixture screws in the second rack of carburetors. Any tips on getting them out?

Not to say it shouldn't be considered, but I have never replaced a damaged carb with anything but another carb which matches the other carbs remaining in place.
Good Fortune!

The more I looked at the bodies the more I saw differences in them from one position to the other. I will just use the body from the same position.
I am left with the other question about how best to remove the idle mixture screws. This one is stripped and seized as well and I am a bit hesitant to try to remove it. Should I just leave it and try to synchronize the carburetors based on its setting?
Finally, I am trying to get the body cleaned up and there is a discoloration at the top of the carburetor where the diaphragm would cover (see attached picture). I have tried boiling it in lemon juice but that did not do much. I have been spraying it with carb cleaner and rubbing at it but again I don't think I am accomplishing much. I'm fairly new at fixing my bike so I am not sure if this is varnish or rust or something else.
The entire tower pretty much broke. I don't think it would hold a screw. I am pretty certain a new body is my only solution here.

Again about the screws, how would you recommend reinstalling them? Some internet research suggests peening them over by using a sharp chisel. Is this how to do it?

For two days I was spraying some of the penetrating fluid onto the screw every 4-6 hours. Today we used an impact screwdriver and the screw came out perfectly.
Happy Endng...

Is red or blue thread locker acceptable for this use? I know if I use the red I'll have to resort to heat to get it out later.
Any comments or suggestions on where to find the appropriate screws? I would like to avoid online as I only really need 8 and do not want to wait for them to ship to Canada.
