You mean Exceleena 1? Sorry to distract from your thread, but can we see pictures??
For what it's worth, if you DO happen to mean Exceleena 2, there's someone on Arcade Otaku making a marquee for them (IDK how close to or far from original they are.) If you need a link to that, someone posted it in my Aero Table restoration thread, or I can snag the link for you and post it here.
Heck, maybe an Exceleena 2 repro would even work on your cab... I've been thinking about getting one for my Exceleena 2, and I'd be willing to have it shipped to you first so you can try it on your cab, then you could ship it to me after you determine that..
