If the measurements of @Simon Says are correct (and I have zero reason to doubt him), I would find a hole punch the size of that hole (well, slightly smaller actually) and pound it down further into the hole. You should be able to pound it down enough to have a new spring still sit properly in that hole. The only other thing I can think of is using the other spring hole (or were you running 5 springs?). If you were running 4 springs, you still have the center hold to use for that 4th spring. I have zero experience with setting those bad boys up, so I do not know if that is a no no with 3 springs being next to each other, but another thought! Best wishes on resolving this.
The hole punch, or whatever is used as a hole punch, size matters. (Yeah!) Like MW says, use something smaller. I’d also suggest something that’s not very hard. (Oh dear.) If it’s too stiff, it may break off in the hole. The angle at which you tap matters. (Really!?)
Using something smaller will let it fall right out of the hole when you finish. (Gulp!)
