They don’t carry them anymore...I looked at every one I could find and even online and they said they discontinued carrying it.
I just measured mine like in the video I posted above and just kept checking and rechecking my measurements until I was at 2 and 7/8 before cutting it with a cutoff wheel. If you take your time it’s real easy...unlike the pipe cutting...you will have to bevel it down to where you get good penetration with your welding.
