I was checking aero fighters on the klov website and did find the conversion class but I can't find the jamma part? Sorry if I am being boneheaded.
Sorry if I offended you, but I
was confirming your suspicion.

I'll repeat, since it didn't sink in that I actually answered your question:
Any cabinet could be any format because you don't know what someone might have done to it in its history. Therefore, you ask the seller, and mystery is solved.
PS: Thanks for the support other people, but I
was being a bit too direct, and I had a feeling it might be crossing the line when I posted it, but some days I am grumpier than others.
