When I am buying replacement parts for my 73 Duster Which store should I use. I want to use the car to drive cross country at the end of summer. I have to replace the power steering pump and a few other items. In my area I have a O'reily, Autozone, Pepboys and a Napa. Which is spread out further in the country, if I had to warranty something on the road. Same thing with tires I am going to get a new set of tires for the 14 inch rims I have a Big O, Pepboys, Les Schwabe, Tires Plus, Discount Tires maybe others, I would have to look to see if there are other nation wide chains in the area if you guys have other suggestions.
