Hey I'm thinking about buying these for my car:http://www.andysautosport.com/nissan...a00100062.html

How hard would these be to install? Would I have to buy a universal bracket like this http://www.andysautosport.com/nissan...r00035634.html

Or would I have to have a shop fab it up

Basically I'm just trying to understand what parts are required to install the seats before I buy them and possibly figure out they don't fit. thanks
