What Rear End do I have?

Hey guys I picked an 08 used in great shape. The only thing I was not able to surmise was the rear end. How do I tell if it's 3.31 or 3.55? I'ts an 08 CC 250 lariat. I tried the VIN look decoder and it din't show the rear end. Oasis doesn't say either.

2008 F250 CC Lariat Shorty 3.73 Limited Slip, manual locking 4wd, Rhino Lining, Custom seat back TV/DVD systems.

I'll check does the code say specifically or do I need to decipher it?
