Fortunately enough another car popped up in Tacoma not long after... and it was even the same color combo as my 6.9.
The only issue was it was a 1976 450 SE, and not the long-wheelbase SEL. But, the body was straight and the price was
right, so I drove it back so it could wait until the 6.9 had been completely stripped.

As you can see, the seat bottoms had seen better days, and there were numerous "creative" electrical changes, but
most of that would be ripped out during the transplant, so I wasn't too worried about it.
Here are some pictures of the 6.9 at the shop when the stripping began:
