Same thing ... the flow of the code is very similar it just changes the constant in the line for where to put this ...

The code is generic and can be run in any shipping module:
PHP Code:
// don't show when over 50
global $cart;
if ((
defined('IS_ADMIN_FLAG') && IS_ADMIN_FLAG == true) || $_SESSION['cart']->show_weight() > 50) {
  
$this->enabled false;

You just need to put it in the right location of the code ...
