I purchased a set of EDO 2425's for my 108-2
many years ago less most of the struts and wires - so I purchased a set
of blueprints from Univair to help me correctly identify the parts I
needed. The blueprints contained part numbers and some design geometry
but lacked specific dimensions.
Unfortunately, a great number of the parts I
came across had no serial numbers on them, perhaps because the stock had
been repaired/replaced at some point. (to be expected after 50 plus
years of flying) Many people assured me the parts they had for
sale, came off a Stinson floatplane; however, no two sets of struts
seemed to be the same length! I called JJ Frey at EDO to see if they
could provide me with the exact dimensions of the struts and wires I
needed; unfortunately, company policy prohibits the release of this
data, due to the associated liability risks involved.
Eventually I found a complete set of rigging in
a barn in southern Ontario. I decided to recorded the dimensions for
future reference and the rest is ... well OK... you get my point. Hope
this info helps you out with your parts hunting/installation.
