I parted out a '74 G20 van a few years ago. It appeared the front suspension was similar in design to the pickups, just a bit wider.

However, some 20 series vans had 5-lug hubs and some have 8-lug, while your '66 C20 is 8-lug. I'd start by making sure the van has the number of studs you require.

You might be able to swap spindles using newer ball joints. But I don't know the particulars of this swap. HTH!

It's true. I really don't do anything but browse the Internet looking for trouble...
