Hey Drop, the part you are looking for is A-19308. It is really rare. An alternative that may work for you is 04-10999 available from Pinball Spare Parts Aus. http://www.pinballspareparts.com.au/catalogsearch/result/?q=04-10999
The only difference is the thickness. A-19308 measures 0.14 in. thick and 04-10999 measures 0.17.
It fits nicely in the bracket.
