yea I found the article Mopar Action April 2013.
Yea they did this borguson box on Gran Cherokees 99 -04.
This box you can get has been Heavilly modified, the use a half million dollar CNC machine to re spline the sector shaft to accept the old stock pitman arms(IN BOTH SIZES).
The mod I was talking about is minor, a small adjustment on the casting edge,to clear the K frame , the claim Boreguson will have tha fixed,also th e fittings are different so they should supply adaptors.
The coupler, This mag opted to modify a stock unit the welded a new borguson supplied spline .
This necessary as the box is slightly shorter than a factory box.
Here is a big thing as to why they dont use a u joint for the coupler.
"One is the upper colummn bearing ,or its insulator /retainor will be damage or pushed out of placethis will destroy the turn signal switch."
"the upper bearing in the chuck will be damaged ."
"The shear pins on the telescoping columns will break,in some cases this will result in a rattle but isnt catastrophic "
I got all this from the mag , not sure if it is true but they dont like the coupler either
