Here is some shoes that will replace the stock shoes. I have the savage replacement, seem to be working fine so far. They are wearing fast though.

Anything after that your looking a three shoe replacemnet and need to replace the whole assembly.

I have had the same skid plate breakage twice, I will be looking into a aluminum replacement soon as it comes avalible. The whole steering assembly is weak with the radio tray and front center skidplate holding the bellcrank post. Any larger hits the front wheels take, these components are going break.

Some people have been reinforcing the bellcrank/servo saver assemble with JB weld and kevlar thread. Here is how I did mine.

This fix works. My son took a large front end hit and broke the radio tray,bulkhead and front center skid, but the bellcrank/servosaver held.
