What's the best years for a parts truck?

[bighorse]

I have a Mustang restoration shop, but a family friend has asked me to help her son locate and restore a '67-72 Chevy pickup. I found a '67 SWB that was in very good condition (very complete, reasonably straight and no rust) for $2000 so they bought it. However, it's an I6 with a 3 on the tree, and he wants a V8 Auto. It's also devoid of power anything and he would like to have PB and PS. I told him that I thought a later model parts truck might be the best way to go for upgrade parts, but since I don't do much with Chevy pickups, I thought I would ask you guys for your expertise.

I have located a wrecked '96 GMC 1500 SWB. It's got a Vortec V8 with an automatic transmission. Is this a feasible swap? What about the disc brake spindles, or perhaps even the entire suspension and steering subframe? Steering column? Brake booster? Auto brake pedal setup? If this truck isn't a good parts truck candidate, what would be good to look for? Thanks.

Here are some photos of the '67. The odometer shows 91k.
