Notice that the front crossmember on the 2wd is located based on axle centerline (CL), which is only possible to find with control arms and spindles installed, and at ride height. It is much easier to locate axle CL on the 4wd frame as it’s centered in the bumpstops.

We can decipher that the factory placed the front axle CL 21.90” behind the core support bushing CL. This is found by subtracting the 16.50” measurement from the seemingly arbitrary line drawn 38.40” behind the core support mounts. This measurement is the same on both 4wd and 2wd frames.
