Michelotto-prepared Ferrari 360 s/n 118115?

I was doing some research into the 2003 and 2004 FIA GT seasons and came across this interesting car:

It was run by G.P.C. and is claimed to have been built by Michelotto, but never shows up in any list of the official Michelotto built 360 N-GTs. Does anyone have an idea of the story behind this car?

 

Thanks a lot! I find it interesting racingsportscars got that chassis wrong since usually the FIA GT races from that era seem pretty reliable chassis wise on the site. Although that does bring up the question of which chassis that Cirtek car in 2005 was, since they both are shown as appearing in the same race:
