Part Identification and Parts Website

Its a 69 273 v8. Thanks for the pointers. I found the part on the auto zone website so I'll be picking it up tomorrow. In preparation I drained all of the power steering fluid. I drove the dart around the block a few times to see how hard it would be without power steering. As I was driving the oil light came on. Does the oil light monitor power steering as well or is there actually an issue with my oil? I know my oil level is a bit low. Going to top it off tomorrow. But, does the oil light monitor power steering as well?
