Compatible capacitors

I have two capacitors on my air compressor that are bad. Both are rated 250V. One is 50uF, the other 70uF.

Is it OK to substitute with one that is rated 370V but similar capacitance??? (I am having a hard tome getting ones with exact ratings, dimentions, connectors etc. )

Yes you can sub for a higher voltage rating capacitor as long as the capacitance is within about 10%.
