The taper on the SJ drag link end is from around 3/4" to 5/8"-11/16".
Doesn't the YJ use the Saginaw "76" box?  I would try to use the stock
SJ pitman arm, it should fit.  The stock SJ pitman arm has about a 1"
drop if that helps or hurts.  Assuming you used the SJ knuckles, the SJ
pitman arm would be a perfect length.

The other option would be modify your YJ pitman arm if you have enough
material.  I use a CJ pitman arm drilled out.  I drilled a 3/4" half way
and 5/8" the rest of the way.  I used a die grinder to make the taper.
Not exactly DOT approved, but it works.
