Seat Holes

Folks,

I am going from bench to bucket.

On the right side, The carpet is actually cut where the hole should be but don't feel a divot or plug where the original bucket holes should be.

I understand the all bodies were built the same and didn't drip out the sports that were not needed.

is there an indication on the floor pan or underneath where they should have gone or do I just measure/drill and hope I got it right :)

Thanks
ian.
