I'd start by changing the gear oil on the transmission. The synchros in the trans could simply be wearing out.

Owners manual states 75w-90 Gl4 or Gl5.
I prefer non synthetic GL4 in my transmissions.

A lot of people recommend Redline MT-90 transmission fluid.

check the clutch free play adjustment, and also make sure that the bracket that holds the clutch pedal isn't cracked... it'll flex if cracked, and not allow the clutch pedal to have full play.
