I got a 1973 dart sport 340 and thinking on changing rear wheels. I have on car 15x8 with 0 offset with 275/60R15 tires. Stock ride height. Thinking of putting on 15x10 with 0 offset on same tire. Do they work with out rubbing?

Same size tire on a rim with same offset, but two inches wider?
The tire will be an inch closer to the spring, and an inch closer to the fender.
Do you have that extra room?
WE can't answer that question.
 
All true above. But the tire will now be wider on a 2" wider wheel.

Get on the ground and measure both sides because the rear axle is usually off to one side a little bit.

Plenty of online data out there to give you some info. A 275 tire will still be 275 wide at the tread.
 
The 275 tire tread is 10.82" wide. The 8" wheel crowns the tread, the 10" wheel will flatten the tread and it will be a touch wider. Note how it shows it will be taller on the 10" wheel. What is poke and inset?

The sidewall is wider than the tread. It is now and it will be with 10" wheel. That photo on the website doesn't show that.

I have a couple cars with 225/70R14's and the tires are very different shape and size form a 5.5" wheel to a 7" wheel. They are not the same physical size at all with 1.5" wheel width change.
