Look at what showed up today. 

J.C. Whitney Part #135858 Selling price $40.99, plus shipping.

This is NOT the way that it fits in the car, but is how it is shipped.

One off and one on.

The mounting positions and adjustments are here.

One of the guys on 6-Pack suggested a dowel across these hinges. I just may do that before I put it in,
but it' so easy to slide in and out, that I may wait until later.

I have to check the width and the fit before I tighten the bottom wing nuts.

That's what it looks like just before installing.

The inside compartment is spacious enough and pretty well put together.

Now I really need that folding cup holder!

OK, this can't get much simpler.  Leave the wings nuts slightly snug and slide it in place.  Then remove and tighten, slide back in and you are done.

That's nice and neat.

This should be just fine with the emergency brake and as it shows in the next two pictures, it is.

There is plenty of room to slide this back and forth after I get comfortable in the car.

A nice amount of space in there, but possibly not as much as another version by BobbyD.  More on that later.

That's about it until I find the folding cup holder locally.
