[s-cars] Alternative to our 4A0 905 351A POS units

[Jerry Scott]

Dave
In your note you refer in the subject to our  4A0 905 351A. In the text 
you refer to the S4 number as: 4A0 905 315A.  Then you mention as the 
Hitachi number for the V6 as, 4A0 905 351.  You later refer to the 
Hitachi number as 4A 905 315.  Am I just totally confused or am I 
dealing with a dyslexia patient? What are the correct numbers?
