Would love to find something! We always have spares laying around because they're constantly breaking.
I looked at a set of RPM steering blocks from a 2WD slash, but the arms seem really short and guy at the local hobby shop said the steering would be messed up.
Now that I think about it though, it shouldn't be too much of a concern. Maybe a stronger servo would be in order.
