Need to remove the headliner from a chevy astro van to install a ladder rack. How do you remove the headliner?

To remove the headliner from the Astro van - you would need to take anything out that attaches through the headliner board (such as visors, clothes hanger hooks, consoles, etc.) - then remove the trim along the edge, front and rear. Once these are removed, the headliner should fall free and can be removed through the rear gate.

A standard minivan headliner kit will fit the Astro van.
