I am told if you were swaping a bench seat from a 80-97 truck to a 73-79 truck you would put the 70's seat brackets on the 90's seat. As for putting a 40-20-40 in...... they use a "pan" that all 3 parts of the seat bolt to. Tha pan then blots to the floor. The pan is the seat brackets basiclly.. I think if you were to cut the "feet" off the pan, then weld the 70's seat brackets to the pan, you would be set. But dont quote me

1992 was the first year for the 40/20/40 seats. They are common in later 1992/96-97 trucks.

My '97 has the base vinyl seat, and that is rare.

unfortunately it's not that simple. The front feet on these things angle down and don't really work in our trucks. The rears, while not a great fit are flat enough to work. The people I have seen cut the front off kinda flat (similar to what I did) and then weld a piece back on that sits flat. They drill a hole through that and a corresponding hole through the floor.

As far as Diesel_Brad's post above - I wish it were that simple. The 40/20/40 seats that I have use 8 bolt holes to put them to the floor. The center seat mounts share holes with the center most holes of each of the driver and pass. seats.

The 70's truck mounts consist of a 1 bracket/slider per side of the truck = 2 total.

I think this can be seen in my mounts for the 99 60/40 bench in my gallery

chase. The 92-97 trucks uses a pan that crosses the whole cab. The 40-20-40 seat bolts in like a bench seat(using only 4 bolts) you are correct for a SD seat though(each seat bolts to the floor)

You dont want to drill all them hoes in the floor. The seats will have no support and will be moving all over the place, on top of that the seats will be sitting at differnt heights
