There aren’t any instructions. That piece does go between the steering box mount and the K frame, it’s mostly shaped like the area it fits into. When I did the two K’s I’ve done I left that piece out. It didn’t fit either one particularly well and would have required some reshaping. On the K’s I did a double row weld filled the gap quite well, and was faster than making that piece fit.
I’ll see if I can dig up a picture of the area in question.
