Sorry it took a while to answer your question, I don't spend much time here anymore, I'm glad it was helpful.
Based on the number of questions I've answered about the mod, I'd say there are a fair number of people who have done it, though I doubt "most" have done it, more likely just a handful compared to the number of C10's that are out there. There are fortunately quite a few tire options still available for the stock front wheel, so I'd say most owners will choose to stay with the stock wheel, but it's nice to have the option. Be patient, I'm sure you'll find a wheel soon enough.
