Hey Silver,
I guess I should have shared a bit more info on my first one. Sorry Guys.... [
] I did the same thing but I used a 1/4 x 20 bolt and blind nut to hold them on. I also put a block of wood in the area that you are showing the red arrow in the first photo. This would allow me to tighten the 1/4 x 20 bolt down well enough that it would not come loss on its own.
