I have the same kit. I never even tried the supplied rod end. I bought the 3 Moog ends I needed and the one end I went to a heim joint end. I run an SOA so I did a modified drag link flip which required something other than a standard TRE on the knuckle side. The Moog's all fit fine on mine. here is a trick for tightening a spinning TRE. take a drift and insert into the cotter pin hole and then use an open end wrench and tighten till it hits the drift. Usually the 1/8 turn is enough pressure to hold the stud to finish tightening the nut. another method is to use a jam nut instead of the castle nut to tighten also using the drift to hold the stud but with a jamb nut you won't get the interference of the slots against the drift pin. torque it down then remove the jam nut and install the castle nut.
