They are fairly low volume - most of what they make goes to the military and commercial outfits from what I’ve heard. You could see if they have any inventory, or can produce another unit. I put a deposit down on these almost a year ago, but testing held up production (assuming they get it right not a bad thing!). If I understand correctly the tracks weren’t what they were testing (they make them for heavier vehicles already), it was the anti-rotation brackets and such. Hopefully I’ll have my tracks by Dec 1 (after they are produced they need to ship them; I’m guessing they may arrive just before Thanksgiving, but that is just a guess…).
