Third postion chords

Hello David I am currently working on level 4 stuff.  I also started looking at Rollin Rhumba v1 in third postion.  I am just curious about the 1,4,5 chords for third postion.  I worked it out I think?? I just want to see if I am way out to lunch.  so on a C harmonica in thirds postion are these correct?

1-D,F#,A  holes 1,4,8 /2",5,9/ 3",6,10

4-G,B,D    holes 2,3+,6+,9+/ 3,7,/ 1,4,8

5-A,C#,E   holes 3",6,10/ 1,4,7,10/ 2+,5+8+

Thank you  

David Saccucci
