I mustnt of worded this correctly so ill clear this up. First remove the Corolla seats and remove the corolla seat runners/ slides from the seats. Throw away the corolla seats. Next get the Falcon seats, remove and discard the Falcon seat runners/ slides as these will NOT fit a corolla. Next fit the slides/ runners from the corolla seat to the falcon seat, if you measure the the seat base frame holes that locate the the slides/ runners to the seat on both the falcon seat and corolla seat you will notice that the length and width are exactly the same, hence the reason they will bolt in with no drilling. This is also a legal swap as you are using the original slides that attach the seat to the chassis. As soon as i get a digi cam ill send pics. sorry about the confusion guys. Dingo
