In reply to galpinos:
Thank you for the recommendations. It's really appreciated. Because this is a modification, rather than a repair. I assumed these two reputable companies wouldn't be able to do anything.
I remember hearing once that there was a little company that does specific modifications according to the customers requirements.
I'm not sure big companies like the two mentioned would cater for this type of modification.
I will certainly contact them if no other companies are mentioned here.
