Ashtray door wont stay closed

[Tejas R/T]

I was wondering if anyone knows why my ashtray door wont stay closed?
I think I am missing a part that goes where the 4 little tabs are (see pic) on the bottom of the ashtray. Can someone tell me what part goes there or supply a picture of what the part looks like? 
Any help would be appreciated.
Thanks Jim

there is a sprint tab rivited to the door , yours seems to be missing , so you will need another door
