Made a Discovery Today(making a cheap HF lock a better lock)
Today i discovered that one of harbor freights rekeyable "High security" padlocks is a copy of an American lock and it even has the same key way and the cores are basically identical, even interchangable. The American key will fit in the hf core but the HF key will only fit in the american core about halfway, probably do to tolerance diferences. I intalled the American core into the HF lock and it worked perfectly! forgot to mention this is the 5 or 6 pin American cores. Pictures below!
