So I managed to file out a small area to allow for better fitment around the trough screw/nut. After filing it open a bit more I was able to get it on...but still not a great fit...I could play with it some more next time I have it out...so few things I came across that you might need to know
the instructional video, while it shows most things you need to know, it doesn't fully explain that you need to remove both the upper and lower opto connectors and place them in their appropriate receptacles on the #8 board. (which he does explain). The #8 board really needs to be mounted as high as you can get it as the power cable was barely reaching the two boards. (in fact I had to relocate it after installing it)
the apron doesn't seem to fit on the original lock tab on the left without giving it a little bend, If I had repositioned the bracket differently It will probably catch better...something to do next time the glass is off.
Which brings me to the right locking tab...its not used and I'm not sure why they designed the right side without the same overhang the left side has and utilizing the same locking tab...my ball got stuck on the right side, a flick of the flipper released it, but I found that bending the apron a bit will probably allow the passage without issue in the future. This is my biggest dissappointment on this mod...I don't know why it was made like this...I'm sure there are reasons.
The stainless bracket...this seems like it also could have been better designed, maybe remove the ball guide above it and incorporate that into it so it locks down to the playfield? the two sided tape is not holding and it seems to be a bit janky as to how it sits there even after I notched it out...but its mosty (mostly at night) out of view...
I've not played with the software and left it stock for now but it looks awesome overall and only played one game where I got a mulitball with the strobing effects...very nice...my 2cents on this..
