Hi, I'm new here. Looks great so far. I need help . I have an older pool, 70's I think. We just replaced the liner and now I need to replace the old vinyl coping. I tried to upload some pics, but prompt says invalid. It's 7 1/4" and clips on the front and back. Anybody out there have any ideas on where I can get something to replcae it with? Thanks for the help.
