1969 M code dart k frame

Thanks for the GREAT Pics! What is the measurement Bolt To Bolt Centerline? How deep are the holes in these bosses? (1" or more?) What are the threads? (3/8" Coarse)? From what I'm understanding, it is the same Motor Mount Bracket as a 383 right? (Just slightly bent?). As far as the 1969 Dodge Truck Shock Mount, how long is this particular piece? Could someone please post some more close-ups of this? (Several different angles of the Left/Driver's 440 Mounting Bracket).


Thanks,

Dan
