99 ranger seat swap

[MyFirstRanger99]

i have a 99 ford ranger xlt, and i finally raised enough money to replace my factory seats. i want to install JEGS GS-1 High Back Sport Seatshttp://www.jegs.com/p/JEGS/755323/10002/-1/10509

i want to know where i could get new seat rails (that will slide back and forth) because my old ones are shot, and will the rails fit the seats or will i have to do some modification?

thanks
rob
