These floats were actually made. The wire had to be bent straight on the clip end to get it apart. The weight was taken off the bottom of an extra weighted float then added to the top. Push the wire back through and with a very small pair of needle nose pliers bend the J back into the wire on the clip end. If the weighs are too thick you may have to get a longer wire.
i picked up 6 of these at BPS today. They are sold in packs of two. I hope they work as well as yours. Looks like it has half the weight of yours.
