OK, I ended up getting removable side art from Rich at ThisOldGame. I have a Mario Bros conversion in a Donkey Kong cab. My goal was to put removable art on the cabinet so that if I ever want to make it a DK Jr I can do that "easily".
So I bought the side art. It costs $75 and takes about 3 weeks to come. No problems so far. A little slow to me, but it is custom. It looks great and is packed very well. Good service overall.
There is always one obstacle between me and my games and that obstacle is me. In this cases, I said "oh, this side art is removable. Therefore I will put it OVER the bolts. This art will be so easy and I will just remove it and replace it. It will live forever and be the best thing since sliced bread".
Long story short, a couple things:
1. Placing over the bolts makes bubbles (duh). The issue is not really the bubbles but really the fact that this throws the whole geometry off. This leads to wrinkles. In the end you have a mess on your hands.
2. The side art can be removed easily. It CANNOT really be reused easily. This is due to two reasons. First, it stretches. Secondly, it begins to lose it adhesive qualities as it is removed and removed and accumulates fingerprints/dirt/etc.
At the end of this process I had ruined my sideart and had to order it all over again. The second time around, I did it correctly and it came out great. However, I realize that this is a one time thing. I had hoped that if I converted this back and found a widebody, I would be able to use this art. That will NOT be the case. Oh, well. It is still pretty cool.
Here is a link to general pics of my MB restore effort:

These pics show the wrinkles and what the side art looks when I pulled it off (i.e. it is unusable).

Hope this saves someone from being stupid like me.
