I am putting a 98 explorer 302 in my 1979 cobra. Bearing in mind I know almost nothing about fuel injection. The injectors were really hard to seperate from the fuel rail and intake. The rubber o-rings don't look to be in the greatest condition and dry. Is there someone that sells new ones for them? Also should I take them to somewhere to get cleaned, or is that not a big deal? The engine is super clean inside, looks really good inside and out. Any other help about using this engine in a early fox would be appreciated. I have an A9M comupter with a 90 harness, I may end up buying the ford motorsport one mostlikely when I do this.

Yes, you can get a fuel injector service kit at about any parts store. You will need 2 kits as I believe 1 kit does 4 injectors. The kit will come with pintle caps, o-rings & filters.
Fuel injector seal kits with 2 O rings and a pintle cap (Borg-Warner P/N 274081) are available at Pep Boys auto parts. Cost is about $2.74 per kit.. The following are listed at the Borg-Warner site ( BWD Automotive ) as being resellers of Borg-Warner parts:
Parts Plus - Premium Auto Parts & Accessories or Auto Value / Bumper to Bumper Quality Parts & Service - Home of the Aftermarket Auto Parts Alliance Group or Auto Parts, Auto Service, Tires, Wheels, Car Care | Pep Boys Auto - Parts & Service or Federated Auto Parts - Automotive Aftermarket
Most of the links above have store locators for find a store in your area.
Use motor oil on the O rings when you re-assemble them & everything will slide into place. The gasoline will wash away any excess oil that gets in the wrong places and it will burn up in the combustion chamber.
The pintle caps fit either injectors with a pin sticking out the injector end or 4 with more tiny holes in the injector end
The pintle caps hold the O ring in place and keep it from sliding off and into the manifold. If the correct pintle caps are used, they do not have any effect on the injector spray pattern or engine performance.
Heating the pintle caps in boiling water makes it much easier to install them.
