CCI are about 2nd longest on the chart. Cheddite are shortest. Either will probably work, but switching between the two is more than likely going to be problematic. (cheddite will probably take an additional shim). The difference in length between the 2 is about .003-.004 there is a possibility they may both work, depending on the fit and crush of either. In my opinion, the headaches caused while looking for an economical alternative, outweigh the warm fuzzies from the savings. You are better off picking one or the other. It MAY or may not work, theres really only one way to find out. But that requires buying, which brings about the feeling of commitment to use... A sticky situation.
