I found this thread. It is your truck, correct?Okay, as promised, d/s lengths- front is roughly 61 3/4, and the one from the X-case to the forward rear axle is roughly 32 1/4.
Would you be able to get some detailed photos of both the right and left frame and transfer case mountings. The thread only touched on unriveting and relocating the frame mounts. I am just curious as to which transfer case brackets were used.
