Trying to help out an anemic Williams E7 that I upgraded to ERR TMCC, cruise and Railsounds. Took a cue from installing the fixed pilot that came with my Atlas F7's. Cut the pilot off the truck and used it as a pattern to make up a spacer. Attached the spacer to the chassis and then the KD to the spacer. Also closed down the coupler pocket with thin styrene. I also removed the cab steps from the front truck and mounted them to the chassis (no swing). Lastly, I ground down the inside of the truck side frames and slotted the mounting holes. This closed up the large gap between the face of the wheels and the sideframe thus narrowing the overall width of the truck assembly. The rear KD was bolted to the boss that originally held the lobster claw. The rear KD swings with the truck.
