Hmm, I did not do either of those things... Could the problem be that while changing the bushings I changed it out of neutral?
I also did not change the lengths of anything. I did see how I could adjust the length of the rods, but didn't think I needed to mess with that since I just replaced the bushings.
The only other thing that does comes to mind is that I took the linkage off their "post" on the transmission to ease the process of putting the bushings on, but I was careful to mark their position (angle) on the posts and return them to those angles when I put them back on. Also I only did one bushing at a time, as not to somehow change up parts or positions of the linkage.
