[ercoupe-tech] Re. Service Bulletin #31

[ebenguiat1]

I have a 415G
   The drawings for installation show two beads on the section of the wing
 where the inspection panels go.
My plane has three beads running lengthwise. 
They look like three tiny hills about 2 inches apart.
 I can feel them if you stand up as if you where to get on the plane 
and run your hand along the trailing edge towards the fuselage. 
I want to get the kit for the installation,   
maybe someone has a "G" model and can give me further info. 
Thank you all,
Prof. Ed
