Wcf – How to convert a basicHttpBinding to a customBinding

I've been working on converting a basicHttpBinding to a customBinding to get my client working on a web farm. I've been fumbling translating the following security section.

<basicHttpBinding ...>
   <security mode="Transport">
      <transport clientCredentialType="Certificate">
   </security>
</basicHttpBinding>
<behaviors>
   <behavior>
      <clientCredentials>
         <clientCertificate
            x509FindType="FindBySerialNumber"
            findValue="..."
         />
      </clientCredentials>
   <behavior>
</behaviors>

I'd show you my translation, but what I've been able to fathom is really undereducated guessing. I will also continue doing some more independent research via the web.
