Installed these bushings the other day along with my home-made short shifter (more on that later) and when I went to tighten the bolt for the shifter I went to the recommended tourque or there abouts as I don't have a tourqe wrench and the shifter was extremely hard to move. The dirrections say about 12-15 ft/lbs. I loosened the nut until I could shift some what easy. Know after driving for a few days the shifter has gotten much easyier, should I go back under and tighten things up a bit more. I didn't think the nut was very tight at all, I couldn't turn it by hand but used very little tourqe with my wrench when putting it on. What do you guys think?
