Help please.

Guys do you know anyone or anywhere i could purchase a front gear box casing that the shock tower attaches to on TRF502X, not bothered about cost as its an emergency. I'm needing it for Saturday 5th March, Scottish Indoor GP. Ive looked everwhere for them and cant find any, Speedtech's got a lot of parts but they're out of stock of this part.
All help will be greatly appreciated
Thanks
Scotty....
