Its time to redo my liner in my ingroung pool. last time I did not replace skimmer faceplate since I could not find a replacemnet and made it work with cracks and all. Now I figure I will come to the pools guys for help. This pool was put in in the early 80's and the only numbers i can find are at the bottom of the skimmer and they are 8650-66. I took the flaceplate off and there are no markings on it. attached is a picture of the sizes and hole pattern
