Facebook might hate freedom, but it's still going strong here.
If all else fails, a reciprocating saw and a die set will do nicely.
Some have a small roll pin on the bottom of the Red FH, very small about 1/16 diameter, if so this can be opened up carefully with a Dremel around the pin so one can grip it with needle nose pliers and pull it straight out... That way if it is threaded you will not destroy the threads while unscrewing it...Good Luck !!!
