Looking for Exterior Door Latches

[Frankshay]

2000 Xplorer: the latches that hold up some of the external compartment doors are getting old, losing flexibility and no longer hold the doors up. (They will sometimes work if I stuff a couple thicknesses of newsprint between the parts to take up excess clearance.) Looking for hints on where I might find replacements?

(thanks!)
