Installation Tips for GMC Savana Owners

• Use a center-blade shear instead of a jigsaw for a cleaner cut and less vibration on the van’s body.

• Always paint the exposed metal edge after cutting to prevent rust.

• This window clamps directly to the van body—no spacers required. It is not compatible with panel thickness over 1/8″.

• Let self-tapping screws create their own holes, or pre-drill with a 1/16″ bit to avoid cracking or stripping. Start with a drill, but always finish by hand for the best seal and to protect threads.

A perfect solution for anyone seeking GMC Savana replacement windows with personality, functionality, and durability.
