Got a 2000 Astro Van intermediate steering shaft at wrecking yard for $10. Upper part fits my 82 Eldorado column (and probably other GM columns) bottom has 3/4" x 36 spline that fits my 74 3/4 ton PS box. First photo shows the astro piece, second the 74 truck intermediate shaft with the cut points shown. Next shows it installed. Astro comes apart and 74 middle piece (DD shaft) us used to splice in. I will pin and spot weld it at the two end splices, the center has 2" to allow for 3/4" movement as the frame flexs. I jacked up each side to see how much movement there would be, simulating running over bumps in the hills. With both wheels up it turns fine with no binding.
