As the title really, has anybody or any of the companies on here done this yet... I have looked and can't find anything.

I can get my hands on everything needed... but not sure on if theres a certain gearbox code id need or what coding would need doing etc.

Any help much appreciated, or any companies that offer this service.

Thanks in advance
