front headliner piece

Im working on redoing all the interior in my 89 astro.
and when I pulld down the old headliner, the front molded piece (dont know what that was made of) crumbled apart and is not usable anymore.
Anyone know where I can order a new one?.

Thanks.

Other than custom building one yourself, either a bone yard or a GM dealer.

there's a huge amount of interior kits out there for van conversions, just do a google search or start with good old J.C. Whitney.
