Ok I think I'm going to give up on the jeep grand cherokee shaft because I have been through so many of them and still cant get a good one. My question is what size fitting would I need to order from flaming river to adapt to my steering shaft. Car is 78 buick regal. Do I need to order two? One for each end? I also see they sell the collapsable shafts but they are like 300 for a complete unit.
