Dimensions are in inches.                            
                                   
(a)-  Bolt hole diameter 1/8 in. larger than bolt diameter.                      
(b)-  See bore chart for wall thicknesses.                        
(c)-  This dimension is commonly associated with "true" lap joints.  Industry standard is to make to the slip on length through the hub.
