Converting bucket to Bobcat style attach

[Cord]

I have a Gehl skid steer and want to covert the bucket to the Bobcat universal mount. You can find the mounting plates on line for a dime a dozen. The problem is that the back of my bucket has been pushed out from the material. It's straight at the current mounting points, but put out between them. This means the flat plate will not fit the bucket correctly. I was thinking about some of the OE buckets and how they used a pocket and tab to mount the bucket. Does anybody have a source for this type of mount?

Looks like I might be screwed. I think the bobtach is actually wider. This means I'll have to straighten the back before installing the new plate.
