Couple issues on my new to me 65 dart…

So, I’ve been having a rough idle on my 225 slant 6. I did a compression test and each cylinder was 120-130 pounds. How does this sound? Plugs looks old so going to replace those. The cap and rotor also look corroded pretty bad. The carburetor fuel inlet brass fitting is stripped. The ID threads on the carb are what is actually stripped so not quite sure what to do here besides get a donor carb for the parts, or buy a new carb if they are still being reproduced?

for some reason, none of my guages work. Speedometer, alternator, temperature, gas gauge, do not work. The lights work, turn signal lights work, but that’s it. I have no clue where to start with this…

while looking under the dash I noticed the bottom of the cowl has rust and an actual hole in it. What is the best way to fix this? Cut the cowl from the top side and repair the bottom side or?

thanks for your help everyone it is appreciated !
