Hot Wheels - those are some pretty cool lenses. I'll have to check them out.
I'm also going to look into the visors from the trucks without electric wipers. I didn't think about that. I'd like to see a pic of that set-up, if anyone has one.
In the meantime, I'm toying with fabricating a simple support bracket, similar to the kind that are used to hold curtain rods. You know, a kind of upside down hook that I could mount in the center of the windshield frame and rest the ends of the visor into. I'm also going to see what I can figure out in terms of a swivel mount for the other ends, so I can flip the visors over to the side windows, in case of glare from the side.
If and when I figure it out, I'll throw a couple of pics up here.
Thanks for the input.
