Loose steering on new power steering gear

I've posted this several times before...
Chrysler Corp. provided majority of funds for R&D which produced what we now know as DuPont Loctite. It was all about these 3 bolts which were a serious problem in early days. The bolts would loosen then ruin the holes in the gear box and the nuts welded in the K, rendering then impossible to fix.They also used bolts with special profile threads ( those also have special heads ) for a while.
