If I remember correctly, HRE and several other wheel companies source their barrels and lips from Triangle Hard Alloys, or Triangle Tool and Die. I don't think they sell too the public though. You might be able to find some used ones online though. Triangle makes the barrels and lips for many brands. Hope this helps. If not, go through HRE.
