Hi there. What is a correct way to disable restriction? 1. Number three and four are useless, i will leave them on the table? 2. Number three is useless, assembly everything else, just leave number three on the table? 3. Install small spacers under restriction and assemble all parts including number four? 4. Something else? Really hard to find good information, if somebody could point the right way to do this, i would highly appreciate it =). Thanks!
