  There are three types of “Sandcast” air cleaner cases. There are both 2-hole and 3 - hole designs. The early sandcast air boxes are held on to the frame by a bracket (stay) which attaches to the air box top by 2 fixing points, whereas the later type has 3 fixing points. The 2 hole air box also has 2 variations.  
  The "Early Production" 2 Hole air cleaner case has no "relief's" or indents to provide clearance between the case and the frame rails. In this case, clearance was limited resulting in cracked cases.  
  The "Mid Production" 2 - Hole air cleaner case did have relief's, however they were not as wide and sweeping as the later production relief's. Again, with the 2 - hole design and early relief design, cracking was still an issue.  
  The late production 3 - hole air cleaner case the differences are obvious. 3 - hole mounting configuration. Wider, more sweeping frame relief's. No depressions on inside of case for mounting brackets. (stays) There are differences in the "stays", detailed lower in this section. This robust new design was less prone to interference issues and cracking.
