Cosic

Alright, a friend who doesn't prefer leathers doesn't want them and is willing to trade me for my EK cloth seats (front and back).
He knows that there isn't a directly bolt on for EK rails in an Integra. To make this swap, he told me to buy whatever is necessary to make the swap.

Are integra rails the only thing that I need to buy for this? Or even, can I keep my EK rails in my car, and his integra rails in his car. Would that work?

Thanks
