The aftermarket seats I bought for the SVO only had holes in the bottom of them to put bolts into, not something that I could mount to the floor. So I assumed all aftermarket seats that were designed for a "universal" fit would be the same. That you would bolt a frame to the bottom of it that would then attach to the floor of the car.

Besides the floor pans are most likely a pretty thin metal that it would be hard to tap threads into, and I might have to weld a nut to the underside of the truck. I don't have a welder or the patience for that.
