[AJD] AR update - cracked

[Chris C]

Jim,
   
          If I am not mistaken (I am at work so I don't have my manuals with me)  The unstyled AR/AO blocks will also work with Styled A's up to serial number 583,999 (when the channel frame went away)  And that all the AR/AO Blocks (272,000 and up) will interchange with the A Blocks serian number 584,000  I am not certain what the serial number ranges are for the 60 blocks that will work with the late A's.  All of the late A blocks have the holes in the bottom for the petcocks,  a lot of people don't realize that because they are out of sight.  
   
                                                           Chris

  The AO/AR blocks are different....one difference being at least on my 1951 
AO is a pair of compression relief cocks on the underside of the block. 
These are accessible through the hole in the frame. I imagine they were to 
be used when the steering wheel attachment was used to start the engine.
