Bench seats with built in seat belts?

I know there are a few choices for bucket seats with built in seat belts, like the Trailblazer, but are there any bench seats?  I will need to add some seating to the Candy Van later and that might be the way I go, if it exists.  All the minivans I can think of have the anchors on the body but my experience is basically limited to various generations  Chrysler and Honda products.  

What am I missing?  Any bench seats with built in seatbelts out there?

In reply to logdog :

Seatbelts go to the structure of the vehicle not to the seat.  Bench seats in pickups will have slots etc for seatbelts. 

But with a van the engine often will protrude preventing a bench seats use. ( unless you have 50 inch inseam) 

Check for seats in the late seventies early to mid eighties full size Dodge passenger Van. I believe the 2nd and 3rd row seats had belts that were connected to the seats. I recently got rid of one I don't if was the 2nd or 3rd row but it did have belts and they were connected to the seat frame. 

03-07 Chevy pickups have a 40/20/40 setup.

Im pretty sure the Econoline 2nd and third row benches are hooked the frame of the seat. Its been awhile since ive removed or added a seat to the work vans, but the seats hook to brackets in the floor too for fast removal

Buick Lesabre 2000-2005.

Its actually a 60/40 split.  This leather has power controls but most cloth are manual.  

Also GM trucks with extended cab.  This is a 2002 Silverado

Basically what I am looking for is a solid bench to go in the back of the van in the third row area.  Ideally it would be one with 3 point belts.  My old Savana had bench seats that popped in and out but the belts were on the body side.  The buckles were on the seat side. 

Next time I'm in a junkyard Im going to take a look around.  I think I remember the Toyota Sienna having built in seat belts but I think it was only on the buckets.  Im sure I can find something with lap belts but I figured if I could get 3 point I would.

I know the back seat of my disco has the middle position belt built into the seat, but it is a lapbelt, not a three point

The third row bench seat in the 2003 Suburban I owned had the seatbelts in the seat. It did have three point belts for the outer seat positions, lap in middle.
