i have the exact same problem.i just got my spintrak today,the weight is attached but,the top is packaged in a bag seperate and it is a sealable type,so the bag can be opened and closed,no screws.
this topic is pretty old as it is nigh on august now,so a few going out without them isnt realy a good excuse as i got mine without,so much for checking when its so easy to insert 2 set screws in the bag with the top.
at least you could say what size the screws are as the spintrak is completely useless with no top attached so people can get their own.
i sent you email today about this.
