Buying car parts on Route 66

[dpp]

I will be driving Route 66 in a few weeks from Chicago to Flagstaff and would like to pick up some parts for my Jensen Interceptor as it has a Chrysler engine. Does anybody know of a good place on the route to buy the parts (I will call ahead to make sure the parts are in stock when I arrive). An advantage would be if it was an interesting stop with some nice cars to see or a workshop to look around..
