exhaust tip question

I have a 68 Plymouth Barracuda that I'm putting an exhaust on the end of this week trying to decide on what to go for with tips. I'd like the original square look, but the guy doing the exhaust does not have them. I could order them but what I was hoping for was that some people could post some photos of the back of their car with various exhaust tips. I'd like to see what some of them look like from the back before I pull the trigger with mine.
