Are you sure they are 1345’s you need or the 1st gen 1200’s? Hell I think they make a 1700 something now for the Max lol. I might still have a 1200 lb bag but it’s not quite 1200 lbs since WM screwed up the dimensions when making it and they had to make me the correct one. They told me to keep the incorrect one. Let me know and I’ll go up in hell’s locker aka the attic and look for it.
