UPDATE. Thanks for all the great info here. Wanted to follow up as I finally got this project done. I picked up the #3 version of the jumpseat as you see in the photos.
That style is an 07-14 I believe. Beyond 2015 it seems they have now changed the mount brackets, so I believe the new ones while cheaper are a no go in these older rigs. I got a black. There are grey ones out there buy not many.
Since there are even fewer in leather I got the black fabric and then bought a new custom fit set of leather covers in DK Titanium off ebay. It's not a "perfect" match to the Pewter leather of 2001 but very close and the covers were a near perfect fit for this seat. It looks perfect. I'll try to follow up with a few more photos that show detail.
Here's some info on what we ran into. Feel free to add things that you have learned.
Father and law and myself spent about 6 hours getting everything in place. Seats came out easy. Hard part was the new upholstery. Material fit perfectly, but they were not slip on's. Had to take each part of the seat apart. It's a pain because of some of the clips they used. If you have a local shop that will install these pre-made Katskin style upholstery for a couple hours labor I would say go for it.
That said it could be done by one person (though having two was a great asset as there was some stretching and pulling involved. I broke a few clips taking the main plastic parts trays, but nothing I could not beef it up with a few screws on reassembly.
Top lis latch came out easy. The latch in the lower lid (seat cushion part) was confusing at first. Eventually I realized you can pop out the metal rod and and handle with a screwdriver (don't lose the spring). It bends the rob a little and you have to bend back, but there and there are screws underneath. Note the position of the spring as you remove, it will save you time.
Once the three pieces were separated, removing the black fabric was not a big deal. But stapling on the new material took time. We hand an arrow style stapler and it will go into the plastic parts, but it's hard for it for they bend. In some areas we used small screws along with the staples to secure. Had to trim a cut a little to expose the screw holes for re-assembly.
The main console came out pretty easy, but the front section (the part with the cassette player) was a bit of a pain. There are screws underneath and we ended up using a 90 degree socket adapter and a flex extension for those 7mm screws.
That done re-assembly was easy and the seat popped right in. Wife and kids had all the mess from under the seats all cleaned out and we bolted everything in.
As reported on other threads, the bolts line right up even though this seat is for a newer truck. The fit is TIGHT once the seats are in. Everything works and looks fine, but you can hear the leather creak when you move them back and forth because they are rubbing tight against each other. Seat back goes up fine, it's just tight in between the buckets. It could be tight enough that if you have manual seats it might be a hassle, so just and FYI.
Having the black plastic parts on the jumpseat (since this was out of a black truck) does not clash with the pewter grey interior. It goes other black dash and interior parts and makes a proper accent.
I will need to close up the duct down below and also there is no power connection for the cig plug in the under storage area of the seat. I'm sure something could be wired up, but no biggie.
I am more focused on the small hollow left by the front (cassette) part of the console below the ash tray. I'm guessing there's a stock cover panel or pop out tray that went there on jumpseat vehicles, but I don't yet know what it's called so I have not found one. If anyone knows that part please let me know.
All in all I'm very pleased. We can not fit the whole family and it looks good in the truck. The #3 model jump seat has great cup holders and lots of storage with the two compartments.
I'll tinker with a few more fine details and try and post some more photos. I also have the pewter console that I pulled out. If someone wants a console I would be interested in selling.
