I'm going to go out on a limb and say it's time to do bearings, syncros and an input, at LEAST.
You may get into needing forks and rail bushings, too.
There's only 1 C-clip to hold the shifter in.
That seller on Ebay is a screwball.
He has the early 1992-1993 Dodge GAS NV4500 shifter stubs listed as fitting the '94-'97 trucks and he is dead wrong, but he'll find out soon enough when he gets bad feedback for selling people the wrong part.
Mark.
