Ok, here is what I ended up with.
Took the section of 10x10 3/16 thick walled steel, cut one side out.
Tried several methods of bending, ended up at shop with a BIG press.
Got it close to my desired shape. Wanted 45 degree sides.
Had the 8 inch channel and the angle iron laying around for a long time.
Pack ratting pays off sometime.

Cut the channel to length, split the cutoff to make end brackets.
Bore holes to match holes used for tooth bar (removed)
Since it is "too wet to plough" I have only tried a couple of digs.
Noticed the bucket with a slight bow so will try with the added angle when
it dries out.
I looks like it is going to do the task that is asked.
I'll let you know. If anyone is interested.
