Fender guards will work. Quality is good, but there are a few differences. The bodies are a little thinner if I recall correctly, and the edge radius is also a little smaller. Nothing big, but you can tell the difference side by side. Mainly a cosmetic thing, but that matters more to some people. I've used plenty of Mighty-Mite parts in the past with great results. If you want it to look as close as possible to a Fender, then you'd probably be happier with Allparts body, Warmoth, or USACG.
