A few months ago I was working on my Xmen Wolverine one day and I had the apron out and on the floor. Unfortunately it was damaged so I had to order up a new apron from Stern (I have a 9 and 7 year old and let's just say sometimes "stuff happens"). Once I got the new one I put the decals and yellow window inserts on from the old one and my Xmen was as good as new.
I now had a plain blue apron that I wasn't sure what to do with. We had recently received our new Tron Pro 2D, and I thought why not put this apron in the Tron? So I took it to a body shop to fix it and paint it black (cost me $75 for this). Terry from PBL can get some blue window inserts so I ordered those from him (plus a few other parts for it: brackets, screws, sockets and molex connectors). From BAA I ordered a decal set and some wire.
I put it all together and below are the pictures of it (the first picture is the good ol' plastic apron that comes in our Tron Pros). It's not exactly like the Tron LE apron because you can't order one unless you have a Tron LE. But you can still order up all the parts you need and you can make a pretty cool looking LE style apron (Terry can get an LE style apron but you'd still need to paint it). When it was at the body shop I also had to get them to fill in and smooth out the 3 spots where the threads are welded in (you can see the spots on the topside of the apron). The decal is a Tron Pro but all I had to do was trim the top of it so it would fit properly.
As for the wiring, the P6 and P7 locations on the board actually work on the Tron Pro. The hardware and software are all dialed in and all you need to do is push the wires in and you're good to go. So the apron lights in my Pro work exactly like they do on an LE. Below is a little clip to show you that they do indeed work (remember to change it to 1080 for quality).
At first I thought the apron looked a little empty without the triangle shaped decals around the windows but after playing it for a week I love the look of it without them. It looks cleaner and sleeker (in my opinion). The window inserts also look very cool when they go off because it's just a black outline around it.
If anyone is interested in putting one of these together for themselves I can post up all the parts you'd need (and where to order from) and what the cost would be. This wasn't cheap to do, but in the end it's pretty freakin' cool!
