JCC seems to have disappeared from the whole forum.
I'll admit that he had a valid point.....where is the actual proof that these upgrades have any value?
Personally, I did weld up my K member and add gussets around the steering box mount. I learned that from Mopar Action magazine. I don't recall where I first read of boxing the lower control arms but I did that too. In the early 2000s, there were several Mopar magazines in print and they all seemed to suggest the 11/16" tie rod ends when doing a rebuild. I rebuilt mine in 2003 or thereabouts and although there is about 15,000 miles on the rebuild, I had one inner and one outer tie rod feel loose enough to warrant replacement.
I am going ahead with the bigger tie rod ends and solid adjusting sleeves from PST.
