While it's unlikely that you can find someone with just the right cone any other footer manufacturer should be able to male you up a set of cones with the right threads on the associated bolts. For example BDR offer threaded cones (not necessarily endorsing a CF cone btw but just as an example) http://www.bdrsound.com
First step is to take the thread of a good cone down the hardware store so you can find out what exactly it is as there are a variety in use -- my stand manufacturer makes footers with options for the range of common threads -- see https://www.grandprixaudio.com/product-page/apex-levelers
Anyway good luck -- look at this as a way to get a better solution than the OEM!
