Hello All,

I’m restoring L4/J3 sn#9866, N69075, 43-1005 and I’d like to add in the X or H tail brace while I’m doing some welding repairs. Figured, why not.
Does anyone know where I can find drawings, a 337, or an STC for the installation?
I’ve searched this forum and the web and can’t find a drawing. I’ve seen the Atlee Dodge H brace but it’s for pa-12 and 18’s. Cub club listed one for the j3 but as everyone knows that’s a dead end. Any help is appreciated.
