So in the pictures you can see that because of the threads not going all the way down on that one bolt, i cant possibly tighten it down all the way. In order to get it tight what should i do. i've contemplated using numerous washers. but i dont really like that idea at all. Or some sort of metal dowel that i can slide over the bolt in order to cover the threads and give me something to tighten down on. of course i dont just have somethin like that lying around either. whats the best way to go about doin this?
