For those who wish to change the subject of this thread, please feel free to do so, just call it something else. The original subject was a discussion about the different plan numbers and it's meaning. My plans and my aircraft are a matched set and registered with RR.
P.S. My engine is back on the KR and the accessories are going on. Orma L. Robbins A&P/IA KR-2 N110LR Southfield, MI
