does anybody know where I can find them... I've googled, and ebayd, no luck. Thanks

 

your best bet is going to be to keep searching eBay for a set of regular corners, get them dismantle them and remove the yellow piece, then swap them for your current ones. I'm recommending this route bcause you might F-up your corners and be stuck with a jacked up corner and hafta find a replacement, anyway. This way, once you swap your cleared corners in, you can pedddle your old ones back on eBay and recoup some of youe expense

 

I use these guys a lot and prices are good too, not an advert obviously just a point out
