Yesterday I swapped out the stock fuel injectors in my 99 SE for 16 hole replacements. That project went fine, but the red clips on three of the plugs disintegrated in the process. How likely is it that the plugs will work loose without the clips and is there a place to buy replacement clips if necessary?

Be fine.
My neighbor is messing around with 3D printing. I am going to get a good one and give it to him to see if he can make them.
Just for the hell of it.
While it does not effect anything knowing they are busted kind of bugs me.
I think they are more for assembly. So nothing gets pulled apart as the Jeep goes down the line.

Thanks for the reply. I appreciate it!
