Just replacing the IRF-510 devices may not be enough. Something caused the failure. Was it
an intermittent antenna connection that drove SWR too high? Or was it a power spike that
punched through the MOSFET structure?
Finding and fixing the cause might be the first order of business, before replacing the damaged

With the symptoms described there is a microscopic chance it’s something other than a shorted MOSFET. You might want to consider replacing both final transistors. Whatever killed the one that is shorted may have damaged the other. Make sure to buy several spares, this may not be the first time you need to replace them.
