Well sorta. This is what I've figured out.
The Tawayama safari truck is a modded crew cab. They basically used front doors to make the second row of seats bigger for more leg room, which is a option to me but..
I'm trying to make it like this pic from Dividing Creek Imports site
. This is my first choice, the second being a normal 130 double cab with a separate bed, which seems to be as simple as getting the B pillars and making a sheet bulkhead from the back and robbing some of the galvanized top caps off my tub.
The way I see it a normal 110/109 CSW is basically a modified 90/88 tub but I don't know this for sure. From the picture it looks like its a 110/109 rear tub that has been modified and attached to the B pillars like these that safari rovers has for sale
and then the rear bulkhead is removed.
I looked at my rovers tub and the piece of metal that the door striker and door weatherstrip is attached to is spot welded to the rear quarters. It seems that the wagon B pillar bit at the top of where it connects to the tub is made to replace it, then the angled panel bit fits in the bottom and completes the quarter. So theoretically I could remove the part on my 109 tub and put the SW B pillar part on it, remove the rear bulkhead and have the 130 wagon.
Keep in mind, I didn't make it all clear in the first post, I am mostly doing this because I need a bit more room for drive line length. I plan to use it for camping and daily driver use, so the wagon will probably more useful. That, and I could always leave the rear bulkhead in and make it a crew cab truck if I wanted too later.
