I know i am late to the game with this clone, but i am here now. I love this when it works, but my problem is the center pin is just a little short. It wont hold that deck in good. I have to mess with it way too much. If i get it tight then it just wont make contact and i end up with OP on my mods. Any ideas of what i can do? Think home depot might have something? Finding these metric sizes is a PIA.
