'Real Knocker Kit For Stern SPIKE/SPIKE 2

Dislike the screech of the synthesized knocker on SPIKE/SPIKE 2 Stern pinball machines?  Want a real knocker in your game just like the good old days?  
This kit includes everything you need to install a real knocker in your Stern SPIKE/SPIKE 2 system pinball machine and disable the screech. 
Along with all the physical parts, you also get a full color installation instruction guide and mounting template.

Installation Note:
The 2 adjustment settings that need to be changed in the service menu to activate the knocker can have different numbers for each game.  The screenshots included in the instructions are from Guardians of the Galaxy.  We are building a table, below, of the setting locations for each game as people report them to us.  Please send us an email if you know the setting numbers of a game that we do not have listed below.  Please note that this table is a work in progress and will be updated as quickly as we can.
