Pickup vs Station Wagon 109 rear chassis

[TimberPig]

There's no differences in that part of the chassis from a 3 door to a 5 door, as stated, the differences are in the front tub mounting points.

There is the right side toolbox to deal with as the filler passes through here on a Station Wagon, but otherwise it will fit and work fine. Your toolbox space will be impacted unless you devise some other route in, with associated rework.

I have both here for reference btw and confirmed before posting.

Thanks for replying all and confirming my suspicion that it is possible

Different related question:

How come some 109 pickups have rear tanks and some have their tanks under front seat with exterior fill?

Any rhyme or reason as to why?

I just did this to my 109" pickup. You'll need to cut out the lower rounded portion of the middle crossmember and weld a flat plate over it (it hangs down enough that it would hit the tank). That's the main difference. On the station wagons, that middle crossmember is square with no PTO hole. Land Rover assumed that you'd rather have the PTO functionality on the pickups than on the SW's. Also, you will need to trim off about an 1" on either side of the "wings" (small steel tabs that extend inward from the spring hanger mounts), and cut off one exhaust hanger mount that's in the way. Other than that, you're good. The bolt holes for the tank are the same and mine were already all there.

Of course, there is the aforementioned rear bed modification for the filler.
