Many years ago I went seat shopping in a junkyard for a 64 hard top I had. I took measurements and went shopping. I found some that fit real well from a Dahatsu, maybe it was a "Rocky" I don't recall exactly as it has been over 10yrs. I am 5ft 10" and 175lbs and they worked well for me. Here is a picture,
That is the only picture I still have where you can see the seats pretty good.
I am thinking I will do some aftermarket seats in my 77 Ute. I have a Mastercraft Rubicon rear bench seat sitting here that was for my 83 Patrol, it is a 36" wide seat. I measured the Ute and then looked at the Baja RS drivers seats to match it up. From my measurements, it looks like the set will fit absolutely perfect with maybe 1" to spare on either side. Only issue for me may be that I will have a rear PO shifter between the seats and may need more room for it then these seats allow. Really nice seats though and like I say, from my measurements are a perfect fit in a Patrol. You will have to make a custom bracket for these or any seat that is not stock in order to mount them up.

And the bench seat, although this is a 40" wide.

I am not sure MC still makes the bench in a 36" wide. I am sure they will custom make any size though, you will have to figure that all out on your own and contact MC directly. I had 3G's in my 83 Patrol too, Master Craft makes very nice seats. I will see if I can set the Rubicon rear bench seat in the cab of the Ute so you can see how well it will fit. While made as a "rear" bench seat it will work great as a front passenger seat in a Patrol.
In my Land Cruiser I have ProCar and love them.

Great seats the Procar, done 15+ hrs of driving in the Cruiser with next to no fatigue.
