Hey dude!
look at this page:

you'd probably need all the bushings. It's a pain to remove shifter assembly without a lift but very much doable.
If it is rusted-out (which I doubt) you'll need the whole assembly.
Go to you local junk yard and buy it cheap (do not pay more that $20 or tell them to keep it). I do not know how much is a bushing set (I'd buy it from a dealer) but the whole thing prally gonna be under $50 with the rods.
Good luck and Happy Holidays!
