Problem: shifter loose in 5th and reverse only??

Hello guys! I am new here. I just bought a 99 tacoma and I am having a problem with it. The shifter gets loose and spins around freely whenever its over to the right by 5th and reverse. Is this a common problem? an easy fix? I am not afraid to get in there and work on it. I do a LOT of wrenching. I am hoping that this is something that I can fix myself. Thanks in advance for any help that you can offer!!!

Im feeling like its the bushing that supports the shifter. I dont recall the name. But its seems so weird to me that its only blown out when the shifter is over by 5th and R.
