Looks really nice, and I know just how much work goes into a restoration like this. There's a couple things that aren't quite right, but they may have been like that when you received the machine and are relatively minor.

I just wish I has saw this post before yesterday as the first item I saw would have been much easier to fix at the time. In the game you received there is a ball deflector siting in top left corner by the Romulan ship. You received the machine with the deflector in this location, however is simply doesnt belong there, it should be located behind the drop target to prevent balls from entering the opening under the Borg ship and disappearing behind the ramps.

I actually found one picture that covers several things I was looking at.

It appears that your two standup targets in the neutral zone are lower than the top of the playfield but this could just be an illusion based on the angle of the picture. I have to admit I had one hell of a time getting these to mount correctly for a variety of reason; I was able to get them into proper alignment (barely) after adjusting the leaf positioning and bending the mounting bracket just right. To anyone that has never replaced these in a STTNG, the space they fit into is VERY tight, there is not a lot of wiggle room to play with.

The Advance in Rank (AIR) / Command Decision is mounted in a position that makes it difficult to read from the players perspective. Even though it fits odd, and bumps up against the corner of the Delta ramp, that is indeed the correct placement, which is why this particular plastic is bent on every machine out there.

On my machine I simply cut the corner off of the Delta ramp that presses against this part, this small piece in no ways effects the strength of this assembly.

WARNING NERD ALERT!

The symbol of the Klingon Empire Emblem aka "The heart of Virtue" is of a trefoil design with the longest blade in the trefoil representing Honor which Klingons hold as their most important virtue; it should always be pointing up; pointing any other way is a sign of shame and dishonor.

Don't feel too bad about this, I have seen this happen countless times:

For those following to get ideas for your own restoration, target decals are much easier to install with the switches out of the game ... and even easier with the switch harness out of the game.
