any Valiant guys.....need help here

I am restoring a 69 Valiant V100 and I need help finding the clips that hold the trim on going down the side of the car like in the pic. the clip on the left side is plastic and the clip on the right is metal. the clip on the right has the stud broke off. They go on the rear door front and rear of the trim piece. I need 4 of them. I need 48 of the plastic ones. all the numbers I have for these are not good. There is a 4227 number on the plastic clip. can anyone shed some light on this for me. Thanks,Bill
