Here's some pics. I annotated the first pic with red lines through the pivot bolt and the pin that goes through the sick at the rail linkage. I think if you get the bend to the linkage correct you can bend the stick where you want if after it exits the hump. Mine is a stock setup, I photoed yesterday when I was under the truck. I recently had the stick out but didn't take pics. The sick takes a couple 45 bends toward the driver, one under the hump and one at top of the boot. I think my stick is significantly longer than the one on ebay, but it looked like the pivot bolt to linkage configuration would work.
