Sure some have done it but you are looking at a custom bracker, adapting your brakets to the seats you get etc etc think fab work. Look around theres prob about 3 post about seats on every page on the Int section.
It all depends on which seats you use if you dont use a direct swap in then you are going to be fab-ing a bracket of some sort to adapt that seat to your rail or the seat and its rail to your floor. If you have the seat and rail then its as simple as drilling new mounting points and making sure they dont pull throught the floor (also you need to measure to make sure they are going to fit, the seats that is). If you are going to be using your rails then you need to use something like flat stcok mark your bolt pattern on it off the new seat weld it up to your rails and bolt in.
