Expert Reply:

There are a couple things you'll need to drill on the frame of your 2003 Chevy Astro van to install the Air Lift Ride Control Air Helper Springs # AL59521.

The first is a hole to relocate the brake-line bracket, which is just forward of the axle; you'll drill a 5/16" hole to insert a self-tapping screw to do that. Next are holes for the mounting brackets, which are three holes for the driver and passenger side - both upper mounting holes and the rear, lower mounting holes.

You can also see this if you take a look at the installation instructions (which are linked below) for the Air Lift Ride Control # AL59521.
