I just acquired a set of OEM chromed grill inserts for my '03 ram SLT. Is there a technique to remove the push clips that hold the inserts to the shell and reuse them? Or do they have to be clipped and new ones installed? I just went out to the garage with the new inserts anticipating a simple task but decided a second or third opinion was in order. Are replacement push clips available separately at the dealer if needed or is there something else that could be substituted to securely attach the new inserts?
