I don't know about the 4r100 behind a 351W, the 97 had a 351, but it is a 97 style and I don't know if it is different yet. I have not measured the frames. I did a number of searches here and didn't find anything. I think there was a difference in the cab floors, but I have the 4x4 cab if i need to change the hump. Does anyone know?

The 351W is from a 2WD, so I know I need a rear sump pan and pickup tube. I hoped that i could find one at summit or jegs, but no luck yet.
