I couldn't find it new.. do you have a link?Mine only had one tab left. I used threaded rod through some of the plastic that sticks out with a strap across the top with wing nuts to hold it down.
I think you should be able to swap the fuse holder/circuit board into a standard Cobalt fuse box but I haven’t had them in my hands to compare.
They are also available new for a somewhat reasonable price.
GM Part Number: 15899326 is available for the 2005-2010 all models but the Turbo SS.... I wonder how different it is...The ones I see on eBay look very close to the SS holders.
