Racing stripes for a 66 Barracuda

I will be going with the gold. Because all the other work, I will be waiting on the re-painting the car (looks good and will have the stripe painted at that time)
In the short term, I am thinking about using a stripe stencil set.
There are a couple out there; Phoenix Graphix, Graphic Express and Classic Industries. And they are all about the same price for the set.
Does anybody have any experience with car stencils of any type?
