Google checkout question

[Eljay]

I would like to submit the manufacturer name to the checkout process when someone uses google checkout. I can currently get Qty, weight, etc according to the array that google chooses from but have no idea on how to add the manufacturer or any other field for that matter.

The files I was able to modify to see changes to the values passed are:
gcheckout.php around line 154

$products_name = $products[$i]['name'].' '.$products[$i]['model']; 

responsehandler.php around line 371

$order->products[] = array (
              'qty' => $item['quantity']['VALUE'],
              'name' => $item['item-name']['VALUE'],
              'model' => $item['item-description']['VALUE'],
              'tax' => 0,
              'tax_description' => @$item['tax-table-selector']['VALUE'],
              'price' => $item['unit-price']['VALUE'],
              'final_price' => $item['unit-price']['VALUE'],
              'onetime_charges' => 0,
              'weight' => 0,
              'products_priced_by_attribute' => 0,
              'product_is_free' => 0,
              'products_discount_type' => 0,
              'products_discount_type_from' => 0,
              'id' => @$item['merchant-item-id']['VALUE'] 

scratching my head to figure out how I can add the manufacturer name to this. Any help would be greatly appreciated.
