The only way I know to do that is to remove the belt for the housing and then cut it off with enough length to have some slack and then you’ll have to fold the cut end of the belt a see it together to hold your belt latch key. Also find an adjuster so that the belt could actually be tightened. You may be able to find the size of the latch and order something like that as well. Keep in mind that is a horrible idea to have passengers in the rear of the machine without a cage unless you’re 100% positive you’re not going to flip or flop.
