need help.....someone educate me here

the clips that are on the car are not available anymore. they have changed so I need to find ones that are 1/2" high. I guess the height is the most important thing on the clips. The old ones are 1 1/8" wide x 1/2" high. The ones I found the closest is 7/8" wide x 1/2" high. I would imagine the 1/2" high fits the inside of the trim piece. 521 restoration has these. going to check into this a little more. Thanks
