I am looking for pictures, plans, dimensions for the rear axle steps for an Oliver 77.   I have found some for sale that have a tool box under them but they are expensive.   If I had the plans/dimensions for the steps without the tool box I would like to make them my self.   I would like to make them look as close to original as possible. 

Does anyone have the specs or information on the steps.    Any information would be appreciated.
