i give up

I've had it. I've mounted, remounted, adjusted, moved, tilted, twirled, jammed, twisted, grunted, groaned, and finally ... just gave up.
I literally mounted and re-mounted the monitor shelf seven times trying to make it fit in the cab, at the right height, and try not to stick out the back. I give up on it not sticking out the back. It's just too big, and easier to cut a hole in the back panel than to re-engineer the front.
The inside of the cab is marked with about eight different angle lines for mounting the shelf. The shelf sits on four 2x4 blocks which are screwed into the side of the cab (I'll take them out one more time and glue them in addition to the screws.)
There's a small block at the back to keep the shelf from sliding out the back.
There's also a brace made from three 1x4's that trap the monitor base. Those are screwed into the shelf.
Looks good for now, time to move on.

My t-molding arrived yesterday at the office, but the ups guy delivered it to the first floor, and the girl there sent it back over to the mailroom in the other building. :(
So, now, I have to wait til tomorrow afternoon for it to get opened, inspected, and delivered back up to me on the third floor. What a waste.

Where the hell is my spinner and miniPac??????? I'm ready to start wiring!!
