I was told by Husky that they plan to add a 2nd row liner for bucket seats as soon as they have a vehicle to measure, they are not located in a large metro so maybe that really is the hold up.
The only 2nd row bucket seat option I've found is a custom fit Lloyds rubbertite hex mat, autoanything.com has them available. I checked and the 6-Pass and 7-Pass versions have different part numbers so it seems correct. I had these in a Scion xB a few years ago and they did an okay job, they are half the price of liners.
