Came alittle late to this discussion.
A few things to note.
1) The new drop targets are short. This needs alot more time to discuss. Will discuss later
2) Pull back the display's on your tray's so you don't scatch the back glass
3) For the flippers add in a washer to put some height back into the resting point
4) You can add the "Gottlieb" board if you want to stop the double switch on the pop bumper during drop target resets.
5) the Long drop target back can be beefed up using a double link, shorted the link and add in the lower spacer. As above.
6) The back bar to hold the backglass. This needs tape on it to protect the glass. Again needs some details.
Anyway that is a start. Lets talk at some point. CS
