Hot Rods Cowl steering using Mopar box question

Hi guys -

I am putting together a cowl steering set-up using a Mopar box AND using the stock Mopar pitman arm as shown in the photos. Question - given the taper on the tie rod end of the stock Mopar pitman arm, what can I used to connect the pitman arm to the draglink?
I presume I can't use a heim joint since heims are not designed to work with a tapered tie rod instead being designed for a bolt.

 

A couple more pictures. One of cowl and one of steering arm at spindle the drag link will connect to.

 

Cut the tierod end off, drill a hole in new end of pitman arm, attach hiemjoint.
