Well I was driving around the other night, and low and behold, my ash tray door, just plain cracked in half.  I should have never touched it. 

I do not and have never smoked, but I leave a spare fuse in there.  NO idea why I wanted to 'look' at said fuse.  But anyway, does anybody have a spare door that covers the ashtray?

 

My cursory search has revealed that this may be a hard part to find....

My 72 has a metal slider? Realized after I did a search that you said yours was plastic? What year is yours? 

Heres the metal one I found for you, but I don't think it will help now that I reread your post.
