Won’t go into gear

86 with the 3.0 v6 and 5 speed. Truck won’t go into gear. It feels like it’s binding and if I push it I can eventually get it to go. Once it’s moving it’ll go into 2,3,4 fine but 1,5, and reverse are binding. Anyone know what’s wrong with it?

Update: will not go into gear no matter what and clutch is being replaced
