When the rubber breaks or deteriorates, it will cause the shifter to fall. Yes, Dcaaff is right, cheap short shifters cause a grind, and random other issues. Another thing for sloppy shifting is the bushings in the shifter.
If you plan on DD'ing it, get all the maintenance up to par, we all know the way these cars are. They can get expensive. I personally have had great luck with little maintenance, but I did everythig right the first time. Don't go cheap on parts, trust me, these cars do not like cheap parts. If you do the timing, do the 120k kit. Get everything and do it all at once.
