cleaning up my 620 to put cylinder in but need little help. Does the cylinder only use 1 metal cap ring on top of glass or is there suppose to be one on bottom too? Also the clamp looking thing on bottom how does it work to stay in place, it has 3 screws with square nuts on them and 1 screw with nut where end should go together but must be broke off as they're not connected am I missing parts is it suppose to bracket to bowl base somehow.
thanks for now Laroy
