Hey Cody! There's absolutely no drilling required to install the TruXedo Lo Pro Soft Roll-up Tonneau Cover item # TX549101 on your 1991 Chevy Silverado. This tonneau cover installs using clamps that grip the rails of the tonneau cover and the tops of your bed sides to insure a secure connection. I attached a picture below of the clamp installed.

The TruXedo Lo Pro item # TX549101 is confirmed to fit the 1991 Chevy Silverado with the 6' long step side bed.

Please note that if your truck does not have a lip and the top of the bed rails are flush with the sides of the bed you will need the Access Original Soft, Roll-Up Tonneau Cover item # 834532000210. The clamps install in the 3 bolt holes just underneath the top of the bed rails.

What kind of gear do you typically haul that you're wanting to protect with a tonneau cover?

On the 91 stepside there are no inside rails. It is straight down. I’m just wanting to to store small items in and for cosmetic looks.

@CodyB Thank you so much for that information! The TruXedo Lo Pro item # TX549101 is not going to work with your truck. You'll need the Access Original Soft, Roll-Up Tonneau Cover item # 834532000210 instead. The clamps install in the 3 bolt holes just underneath the top of the bed rails. I've linked an installation video below that we made on an '89 Silverado with the same bed.
