I am looking for body panel clips and grommets equivalent replacements.

Parts like MB0088341 ; MR167003 ; MR250761 ; MU470013. They are just plastic or metal inserts to snap into the metal car body in order for screws to fasten into and hold interior body panels. I've check with multiple Mitsubishi dealers and all said the parts had been discontinued.

However, I'm sure auto repair body shops would have something equivalent to use, when they repair an older Mitsubishi vehicle. I'm just not sure what they use and what can be used as replacements. Thanks for any tip!
