Set fields in uc_addresses checkout pane to disabled I want to disable the billing address fields in uc_addresses so they cannot be altered by the user while they're checking out.  However, I cannot find a form to use hook_form_alter on.  It seems those fields are living inside a pane, but I don't know how to isolate and edit that.

I suppose this is one of those times they told me about where all I want to do is hack the other modules.

edit1:
If you're interested here's the function that controls the panes and calls up the form.  I don't really understand how it works.
It must be a form and You can alter via hook_form_alter.
But in function you should must check the form_id and after that print_r or dpr or dsm (whatever you like ) the $form. And search for the address field and unset it.
