You said you werent sure of the 3905 steering assembly fitting the G3 chassis without modification, right?
I said you may need to shim the posts a little (at the top or bottom) to remove any slack, since the 3905 front skid has mouldings on it to remove any slack, where as the G3 skids are just plain metal with no such mouldings (have a look at the exploded views on the traxxas website).
If you managed to fit the steering to your chassis without any problems, then you needn't have worried or asked about it in the first place- ask for help as issues arrize normally, unless you are certain you are going to run into problems, in which case someone is likely to have a solution (emaxx has been around for so long any and all eventualities are pretty much covered)
