Need help with power steering gear mounting nuts on K Frame

The whole story, Problem was they didn't or couldn't keep this land that the steering gear sits against flat enough. The bolts would work loose then break the welds.
When Chrysler Corp. provided majority of funding to develop a thread locking chemical product, it was all about these 3 bolts. So we can thank Chrylser for Duponts Locktite. Beyond, or while waiting for that, there were also 3 special bolts with special interference thread pitch and special heads to identify them, used for some number of years.
They did eventually figure out how to weld 3 nuts to the back of this land and keep it flat.
No matter how you fix it, check mating surfaces for flat, clean, and dry.
If this early K was mine, I would start a parts wanted thread for those 3 special bolts also. Good luck with it.
