Headliner conversion kits

Anybody ever use one of these? I'm looking to put a headliner in my 64 Dodge Dart 4-door. I have my bows, and I think I could probably install a regular headliner kit, and I'm helped by the fact that my back glass is already out and my front glass is going to come out. However, I have seen these "conversion kits" in a couple of places, and while some cost as much as a regular bow-style headliner kit, some are about a third of the price.

On the second one, I'm actually not sure it includes the cloth, and when I called JC Whitney, the person I talked to had no idea.

And here are directions for how to install the conversion kit, though the kit this site sells costs more:

Anyway. This is appealing to me for two reasons: one, it looks easier than a regular kit. Two, it looks like it could be cheaper. All I want is for it to look okay; it doesn't have to be perfect or even appear "stock."

Anybody ever use one, or have any thoughts on this?
