These worked for me. Inspired by Smogtech's thread, hes the man! Have 2 on each side. Put red thread locker on while you do it. Mine dont slip. I think the size of it was 3/16 as opposed to your 1/8.. something like that i forgot.
I would never consider those du-bro pieces, r/c planes yah, but your life? no way. I'll take pics someday of mine, my friend did a clean simple job. No need for custom brackets etc.. just drill and bolt to hold the z32 line up.
Well im probably due for a check up since its only been on for a week, so Ill see how it has been holdin up.
