I am trying to think where Skystar stamped the serial number on my Classic IV
Was it on that triangle plate welded to the fuselage, where the 2 seat belts are bolted to. The one in the middle, behind your shoulder.
I may me totally incorrect of where, but almost positive they placed a serial number somewhere.
Sorry if I am wrong.
After I posted this I had another thought. It could be on this triangle.
