How to install a short shifter in a 1991 Honda Crx?

[Nick]

I have a 1991 Honda Crx si and I'm looking at a short shifter on craigslist. I've talked to the seller and he knows it will fit my car (the crx has a b18a1 engine swap). In the picture al he has is the shifter, so I'm wondering if that is all I'm going to need since he works on Hondas and knows it will fit. I'm not sure if theres supposed to be any other parts like bushings or anything like that. I don't know much about cars so thats why I'm asking this question - thanks for your time
