I have read that Ford came out with 2 different chrome 95 Cobra R rims with a slight difference to the spacing between the spokes.....M-1007-C58 and a newer model M-1007-C50. I have also read that some were made in Japan and others were in fact made in the USA. I have also noticed in various pictures that the older C58 wheels have lettering around the valve stem, and the C50 wheels did not. I'm pretty sure I bought a C50 rim since mine does not have the lettering. (An example can be seen in photos in this thread) Differences in Cobra R rims - SVTPerformance
I bought what I believed to be a used Ford Racing Cobra R rim on Ebay, but cannot the part number of M-1007-C58 or M-1007-C50 stamped anywhere on the back. Now, I DO see the Ford logo cast into one of the spokes and MADE IN THE USA. The other things I see are attached in the pics. I would greatly assume this rim was IN FACT made by Ford with the stampings I see, but where is the Cobra R part number of M-1007-??????
