Hi, thinking of getting my MC21's steering stopper repaired.

Looks like its been down and pushed back abit, had a close look and seems to have a very fine crack around the stopper aswell.

Does anybody know any good repair companies and how much it will cost? I want it done to a very high standard, so i dont want to use a back street car welders or anything like that.
If i can get it done, im thinking of building a project mc21 with the swingarm i also have.

Radial zx636 forks, and undecided on engine at the moment because of used mc21 engine prices, but i may leave that until last.
