I like the idea of the vinyl caps too. At least I know there is something out there if I can't find regular dust covers. Mine are just cracked right now, but they are trying to hang in there. I noticed that after my last trip around the block that one of them had moved itself down after the forks compressed. I was thinking about electrical tape or a zip tie as an interim fix. I was just hopeful that someone else had found real dust covers that fit.
