Chrome bumper end caps

Hi guys i have an 82 gti and I bought it with chrome bumpers already on it, but I am missing three of the end caps. I have looked on all the websites and can't seem to find the same as the one that is on the car, it has a bolt on end cap on the car but everywhere I look they seem to be clip on. Can i use them or does anyone have a website or some they would like to sell.
