Well I can tell you that yes they do have them, and yes that is the correct number.
I ordered mine about a week ago and installed it (well 90% of it anyway) yesterday.
There are a few issues that I am in the process of fixing, but for the most part it should be good.
The unit is a 4 panel and not a 3 panel, and the installation instructions they send you is for a 2010 model year not the 2013. Heck it's not even the 2012 version! LOL......
Here is a link to an install for a Rambox, but it isn't identical to ours.
I'm hoping to fix my problems on Sunday, so if you want to wait until Sunday night I can let you know if I fixed them before you order one.
As a side note, I ordered mine from fastNugly and got it within 4 days I think and at what I thought was a pretty good price.
Sorry I only have a night shot of what it looks like on, but I can take more pictures later with full details.
