He has a 4x4 lwb, which has the same frame as a K20. THe difference is in the axles and springs. I believe the D44 front axle has thicker tubes on the
K20.

The 70+ axles are open knuckle, which would be an upgrade from your 68 model. The K20 rears are all good, the eaton can be a little tough to find brake parts for, but ~$350 or so and you can have an all new disc brake setup added.

I may have an extra set of axles here from a 71/72.
