[Starlight]

The last gen 3 i worked on didnt even have that flat surface ''block" there. It had a round edge. Would have been very hard to do on the one i was working on but maybe yours will be different. I guess crawling under the truck with a flashlight would tell you if it would be possible with yours or not. Also would have to be machined pretty accurately to install the pin thats located behind it.
