XRAY - Model racing cars

hey just wanted to know if any body has come across this before, got a kit 2011 NT1 from a mate I race with still sealed in box, I have just started to build it and when doing the diffs last night I opened one of the kits and the O-ring was twisted up like a cork screw, and I cant get it to relax into a circle at all, the other diff kit was fine O-ring fits straight in, any ideas on what to do? before I order a new one, (not happy with Xray my other kit had wrong springs all rear springs)

I think Xray need to keep it separate or at lease put a spare one in, now I need to wait to get it running

Try twisting it around with your fingers! Put some silicone oil to try to "stick" it into place before mounting the diff cover.
