well I will tell you this...
First you will be told to convert to ball screws.
Then you will ask about mounting motors and such...
You will be told to use the search function (which is handy by the way) and search for grizzly conversion.
Once you do that you will most likely find hundreds of threads from people that did exactly what you are asking about. Those threads will also most likely have pictures and details that you will want to know.
To be honest, it does not matter what kind of mill, or the manufacture (most the time) they all have the same basic things done to them for conversions.
So get to searchin.
