Devil's advocate: Carefully clean it up, find two old five spokes for the front and then leave it alone. Once it's been restored it's not a time capsule anymore and it becomes just another (yawn) rotisserie-restored '68 Z/28.

Reality: It's just not worth that big bag of cash unless it gets a rotisserie restoration. The auction houses won't let you park it on the property, let alone put it on stage until it looks like all the other rotisserie Z/28s. As it sits it's just another (yawn) slowly rotting '68 Z/28.

I'd go with the Devil's advocate!
