Does anyone make the spring for the key release collar?

@MoparMike1974 How far did ya get? What did you end up doing? I'm in the same boat! I purchased the repro collar pieces (real nice I think) and painted using Herb's Interior paint (perfect match green), all ready to go back together - but I need that damn spring.
Yeah same, i didn’t know there was a spring, so mine is installed, and it just kinda flops around.
