It appears that the OEM spring fastener was two plastic rivets through the spring holes.
I put JB weld on the plastic and pressed the spring. Some JB weld came through the spring holes.
This created two mushrooms of JB weld on the top and it looks like the original plastic rivets.
The two screws that Harley8029 did looks like they will be stronger and hold better than what I did.
In the event that the JB weld does not hold I'll probably just say..."Ahh screw it!" and be done with it.
