Yes Mark I sure did and will be selling my LPM box.

Riccardo is correct. The LPM pieces do not line up with OEM air boxes. (see pic) I thought I could use the centre piece but no go. I'm going to sell my LPM box and get the new 2 hole Yamiya. (wish they came out earlier).
As for repairing the box I did some research and consulted with various people and concluded that the best product to repair a box was with ABS as the box itself is ABS. Plumbers use ABS cement (abs and acetone) to join the connections in ABS pipe. It melts the joint and bonds almost instantly. So here's what I did.
After a bit of experimenting with old side cover pieces etc. I wasn't very happy with the outcome. I needed a lower tab for an original side cover so I bought a set of Yamiya re-pops. The right side cover is going to be the donor for the lower tab and some of the rest is going to the repair of my air box. I just cut it up into small pieces and let it soak in a clean metal can with acetone until it melts. I mixed it thoroughly and diluted it to the consistency of white glue. (Used by carpenters etc)
Next I prep the areas to be repaired. If it's a crack, drill a small hole at each end of the crack to stop it from "running" after the repair. Now grind material out along the crack with a dremel or similar tool. Do this both on the outside and inside of the cover. This will make the repair much stronger. Take a small paint brush and load it with your ABS acetone mix. This part you have to get the hang of. "Flow" the ABS mix into the crack. Go slowly. Too much and you will melt through. Too little it dries fast and you can't work with it. It takes a bit of time to get the hang of it. I had nothing to lose. Once my box was stripped I found the the damage was severe and what I thought would be impossible to repair. I was encouraged by the guru’s on this site to preserve every original part if possible, so that’s what I’m doing. It may never get used but it will shine a nice Candy Apple Red.
Once your rough repair is complete, shaped and sanded the next thing you can do is to smooth and fill areas with the abs mix. Just dilute the mix a bit more and brush it on like paint. Be careful not to melt through! You have to be patient! Once your bad areas are built up you are ready for final prep and paint just as you would with any other ABS piece. No fillers, no foreign materials.
Attached pic’s of what I thought was a pretty good 2 hole box when I got 576. A different story when I stripped it! The other pic’s show the missing pieces. (They had filled the box with fiberglass and bondo) and a bit of my repair thus far. Good luck!
In the last pic you can see the relieved areas along cracks still to be repaied. The repairs are still in the rough. I put this on the back burner for now. I'll post pic's of the finished box.
