Need replacements for Trillium Jubilee

[spydmobile]

Hi folks, I have been plugging away at restoring this old girl for years, but the UV has finally had its way with the plastic parts, most of which i can find parts for, this door latch however, has failed many times and may not last many more opens so i try not to open the door or risk not being able to close and lock it again, can anyone recommend a place to get this part? USA or Canada is fine, but i just need to replace it, I dont even care if its the exact same as I want this to be function more than I want it to be authentic. thanks in advance for any help.
