I do not have the specific technical info that you need, just that this question has come up often on these forums, and that it can easily be done. Best to get the details from some who has the direct experience. Someone ought to be along here sooner or later.

EDIT: Here is part of a post from another forum ...
Try Billet Worx here is a link to their web site.
