rear blade replacement edge

[silvertramp]

I backed into something with my scraper blade and bent the moldboard which cracked my cutting edge. I have no idea who the mfg. is. There are no markings of any kind. It's a 6'x6" edge with holes centered from each side @ 3"-6"-18" & 30".
I googled around and didn't come up with a source for cutting edges. Any help locating a supplier would be greatly appreciated.
