The problem is that without the bracket there is nothing to retain the SSD with a mounting screw. Possibly you could jury rig the SSD onto the motherboard and secure it with something like double sided tape but that is a very haphazard way of mounting and you cannot be sure the drive is secure. The second problem is that the SSD in the location should really have a heat shield to dissipate higher temps. The bracket, just for your information, can be found at Amazon here and eBay here but you already stated that is not acceptable.
