Had a friend come over to ask me where to get a new "tank" for his friends Ironman. Apparently is was cross threaded and forced, breaking the tank. Is there a flat top with 510 connection that can be bought for it to just turn it into a mechanical vs. a hybrid? It would give him more options and probably be cheaper. He is a new vaper and was given the mod. He said they weren't making the ironman anymore and I looked around, and found the mod, but couldn't find a new tank/top, and don't know the exact dimensions to suggest a flat top/510 for it, or if that is even an option. Sorry if this is cryptic. I only got to see it for a few minutes and am not that familiar with the mod. I'm sure he could call SIgelei, but he asked me, so thought I would see what I could find. Any help would be appreciated.
