The trim and clips are still available.
Any competant auto glass shop can R/R the trim and not damage it.
New OEM windshields (without the shading band)are NLA as far as I know, but aftermarket windshields (with the shade band) are available. Call around, one will turn up.
Rhett, if you need an OEM windshield, you can probably still find one somewhere, but be prepared to look under rocks and shake trees...
