Will this work to replace a goodman # cap050450440ct? i'm not sure about the difference between the "ct" and "rt".

Those are the same parts. They are both round capacitors rated at 45-5uf 440 Volt. Either part will work.

Does this model cover 370 as well as 440?

This is a 440V capacitor. If you currently have a 370V, you can go up to 440V with no issues. However, you can not go from a 440V down to a 370V, it will cause a burnout.

can't make out the label entirely... everything looks like a match except i can't confirm the +- spec. my old one here says +-5% what's this one?

+-5% is just a variance in tolerance....should not be an issue from one to the other as long as you are matching uF (microfarads) and the VAC Rating....dimensions can differ

Will this fit a model #gsc130361a? serial #060304832??

I believe it will. A lot of Goodman A/C's use it as a replacement. If you Google that model number you will see that capacitor replaces the original one.
