Not all corners are the same. The radius of the curve is different, the tabs or ears for the screws are different..the length of the ears are different. Mine look like the same ones on my Acoustic amps, narrow ears flaring out, 3/8" radius. I was able to buy 8 of them from Vetchking on ebay. He said he had more but I have yet to hear back from him. I wanted to buy a couple dozen since the ones on my Acoustics all look bad, like a poor chrome plating job. The Sunn ones still look good...just scratched up.
