Roush F150 Upper Injector O-Ring HELP!

I was installing a my new I/C Roushcharger kit over the weekend and ripped one of my upper injector o-rings (the one that seats to the fuel rail) , there-for having to replace. The problem is I CAN'T FIND IT ANYWHERE! I'm dying to start this beast but can't because of this issue!

My question is - I've read that the o-ring is the same style used in the 03-04 Cobras so I went to autozone and bought the o-ring (same one's used in the 04-08 F150s anyway) but this didn't work as a replacement due to the inside diameter being much larger than the injector "neck", so the injector just wobbled in the fuel rail!

Also, from what I understand, the injectors that came with my kit are in fact 38lbs NOT 39lbs like the cobras.

Here is the part # for the injector - R07110002 per Roush's instructions, if anyone has an idea at all of where I can find this 2 cent part I would greatly appreciate it!
