Just a word of caution. We measured our screw pattern where the wings once were and determined that we needed the 9" x 42" wings on our 1965 (don't know model). All was well and good until we went to mount the wing on the street side. Too long - it blocked the louvred window of the upper bunk. The problem was we based everything on the screw pattern and didn't measure both sides to see where the 42" length would land. We made the wings out of wood so it wasn't a big deal to just shorten them a few inches but if you are buying used or having them made be sure to measure on the bunk window side. We thought the 9" high wings were only made in the 42" size - wrong!
