Before we go to the trouble of trying to make a patch piece for the hole in the rear floor pan from scratch, does this floor pan look like any other that we could use for a donor? I looked all over the 'net but looks like the 40 series floor pans are pretty different as well as the 25's, and the LV rear is definitely different too. The ribs are about 1.25" wide and spacing is about 3" edge to edge. Kind of looks like the pattern on the 40 wheel wells i think but i don’t have one to confirm. The problem with those patch panels is they’re too short, so we would need to cut it all up and patch it but i guess it’s one solution.
We will have to replace the existing wheel wells completely too as it looks like at some point someone just put new metal on top of the rusted stuff, but those shouldn't be too bad since they don't have any ribbed "features" like the floorpan.
Looks like we will also need to replace the bed support cross channel in the rear of the vehicle, its in pretty rough shape. I see that
CCOT sells them for $200+ for part "B". Before I order one of them - in the unlikely event that anybody has one "freed up" (thats the hard part) from their body let me know. We could make one of these, but i'm sure it'd be easy to be into it for $200+ with time and materials anyway.
I think we are leaning towards eliminating the battery access hatch underneath the front passenger as well and moving the battery to the engine bay. Best as I can tell it's not original to the truck (or at least the current box is a homemade job), and the
FJ28VA looks like it had the battery in the engine bay as well. The FJ28 parts manual shows that it had a frame mounted battery tray but it was on the driver side, and there's no evidence on the chassis that this one had one over there - the parts manual seems to be for more of a general FJ28 chassis but I know there were probably 4 variants of the 28 (2 door, 4 door, pickup, and the FJ43ish variety that FJ Co has right now). This also simplifies one of my bigger head-scratchers as I wasn't completely sure what to do with the front seating because of that access hatch. Would have had to have some sort of hinge mechanism and my preference was to use the LV seats that I have (thanks to
@Tancruiser for helping me find them) to "Keep it Gifu". But that also means we have a big hole to patch in the front floorpan. Fortunately the front floorpan does look pretty similar to the 40 series so I can probably buy a CCOT patch for that one.
