If I remember correctly I used 3/8" female spherical rod ends from McMaster Carr, drilled and tapped them out to 7/16" and used 7/16" rod. I did this on my CompetionPlus in my truck, and the Ramrod in the Duster. Be prepared to do alot of mock ups, and head scratching, as there is not much room to fit everything into the shfter body. I had to use jam nuts and trim all the bolts. Its a tighter fit in the Ramrod than in a Competition Plus. Good luck.
