One of my vivitar 285 flashes fell over a while back while on a tripod, and the shoe part broke. Its finally time to get it fixed. I found a bunch of auctions on ebay for metal hot shoes, but they are not responding to me to let me know how hard or easy it is to put on a flash. I am guessing you have to cut off the bottom part of the vivitar flash? I was just wondering if anyone here has done this.
