Just been lurking and reading here, having no prior knowledge at all of JL T-45's, but all I can say is HOLY CRAP!!!!!

I assumed the 'anti-rotation' pins were horizontal from the get-go. I cannot believe a manufacturer would think a vertical orientation in a thin stab would allow for adequate length of the anti-rotation pins and sufficient support from the wood mount blocks for the pins (especially if the wood is balsa!) Good grief.

Seems to me John's mod here would be a mandatory "Airworthiness Directive" for the JL T-45. Horizontally oriented anti-rotation pins that can be made nice and long seems like a no-brainer.
