Hi again.

I am assuming that these are bucket seats in the front. Here is the procedure for removing them. Please let me know if this looks correct.

Seat Replacement - Front Bucket

Removal Procedure

1. Move the seat full forward.
2. Remove the seat belt anchor bolt from the front seat assembly.
   
   
   
3. Remove the front seat mounting fasteners and tilt the seat forward.
4. Disconnect the electrical wire harness and remove the push-in fastener from beneath the seat.
5. Remove the seat.

Installation Procedure

1. Install the seat into the vehicle.
   
   
   
2. Connect the electrical wire harness and install the push-in fastener beneath the seat.
   
3. Install the front seat mounting fasteners. Tighten

   Tighten the fasteners to 45 N·m (33 lb ft).

   Important

   Verify that the shoulder belt is not twisted.

4. Install the seat belt anchor bolt to the front seat assembly.

I also have a diagram I found at gmpartsdirect.com that shows the parts for the front seats.

Please let me know what other information you might need.

Take Care, Greg A.
