Most people don't just have this stuff laying around. Your best bet is to call Steve @ Tousley Ford. His screen name on here is FORDSVTPARTS and he sells everything for 10% over cost. I bought a ton of stuff from him during my engine build.
my engine is at modular performance and john gets a deal on them from ford also but I was trying to save some money and find this stuff used. Even with the 10% it is still expensive it was worth the try at least.
