The rivets are listed on Pinball Resource web page: http://www.pbresource.com/tools.html
Steel plate A-1826 also listed: http://www.pbresource.com/pfswitch.htm
There was someone on Mr. Pinball selling the A-4345 blade from a Nov 2018 entry (I assume he has more than 1?). (In case Steve doesn't carry these.)
