71SCJ, I guess you can tell by the number of responses that the part numbers you need just aren't out there. I've checked several sources that specialize in obsolete/NOS Ford parts. A few private listings I saw were at least a couple of years old. What is surprising is the number of lower C7OZ-A boots that are available. Seems as though everyone has those.
About as close as you are going to get to NOS would be to use a MOOG upper ball joint. They have a OE line of replacement parts, are the official supplier to NASCAR, and manufacture Ford's Motorcraft line of steering and suspension parts. Probably not the answer you wanted to see, but at least gives you another option.
