Fatman has an IFS kit that uses 73-87 components for 8 lug trucks.

On another note, 03 and newer GM vans have a frame that's slightly over 34 inches. The problem with it is the track width is way too wide for an early truck. The factory track width is around 67" but they have positive offset wheels. The axle WMS is really about 70".

What I like about the 03 and newer van chassis is how the front suspension is configured. It looks almost identical to the MII kits that we're all too familiar with. It may be possible to narrow and graft the van suspension to an early truck.
