Yeah the factory's have to give you enough length to run all the possible locations and yet make them short enough also. The tekno ones can be a bit tight because of the extra length. Use a body ream to chamfer the rod ends before you screw in the turn buckle and use some Chapstick or other lube.
Those are all things I do on every build, still a pain in the butt to thread an inch of rod in each cup. Hopefully I can find some ballcups locally (hoping Revelation has some).
On the plus side, the 17mm servo saver nut was brilliant!
