Can I replace my CAT bucket teeth with wider grading teeth?

[Devlh Laveighn]

I have a CAT bucket with 7 digging teeth and would like to replace them with wide grading teeth (around 200 mm / 8 inches) for grading and ditching instead of buying a new bucket.

Is this possible? If you've done it before, where did you buy the teeth, and did they fit without any modifications?
