I believe it could be accomplished from these people:

If your information is complete and the VIN displayed you could maybe accomplish it with just a snapshot of yours.
It might also be accomplished in this fashion. Since most ZR-1's share similar options with the exception of tops you could find another with correct color, interior, top options and have that one duplicated with your VIN. You might need to supply maybe both snapshots but I'd think it doable.
I have never had these people do a SPID label or even asked if they could but I believe it's likely.

Here's a direct link to their samples and there's SPID labels. All you need to know is their requirements for duplication! Looks like you're "all set"!

If they'll accept a snapshot of your "demolished" SPID label I can provide you a list of the RPO's recorded to the VIN. I would think there would be Registry members who would happy to help. If it's white/grey I could maybe help.
You might post a snapshot of your "demolished" label!
