Derek Spear Designs DSD Button Box For Fanatec CSL Elite Wheel Base

I was sent these images by Derek himself as the CSL product line is unreleased yet and that is why there are no images on the site . I've ordered a left side option A for my Elite wheel base and have been in communication with him about it. The bolt size is M6 and it should be anywhere from 15mm to 20mm in length. He told me that he believes that to be the length, but I should use my best judgement. It is bolted in where the bolts are located for the static shifter add-on. Here is a close up of the left side. I believe that box to be "OPTION C", but don't quote me on that.

Here is a front picture showing both left and right boxes.

A picture taken from the right side showing the right box a little more. The right box is an OPTION A.

Here is a picture of the actual button box I'm getting. I opted for the left side which is "OPTION A". The boxes retail at $130.
