Well the link I posted is a FD24L, so it is not sure if your SSC aspherical would be the same. My 85L does use exactly the same method to fix the focus ring.
Well if your SSC aspherical does not use this kind of contruction, then the only other cause of a loose focus ring (that I could think of) would be likely due to deterioated brushing. Please see Pengland's posting in this FD24/2 thread. Someone is selling these brushings on the Bay 1 2. I don't see any specified for the 24/1.4 aspherical, but looking at the offerings from the seller, these brushings seem to have only serveral standard sizes (across different lens). As long as it fits yours....
Oh no! I forgot how the SSC's focus ring is fixed! Please go to Taiwan's Bigeye to see an example of 55/1.2 SSC. You will have to use a rubber tool to remove the plastic front name ring, then a len removal clamp to remove a copper ring. After that, the front barrel (with filter thread) simply comes off to expose the three screws that holds the focus ring in place. You just need to tighen them and add some glue to fix them in place.
Best Luck with your conversion.
