?what will fit?

[69nova]

I have recently added to my collection a 67 c10 swb fleetside that has an inline 6, manual brakes, 3 spd in the floor (converted), with 6 lug axles. I want to turn this one into a daily driver. I could get a 86 gmc full size van for little to nothing (just haul it away). I was wondering if any of the parts from the van will fit with out any major modifications such as the rear axle (whole or just 5 lug axles), power steering box, and front spindles/brake assembly. I could go crawling around under the van but its been sitting for a while and bees have taken over. I'm sure that someone has looked into this era vehicles for parts but will it work. The van is drivetrain complete. I am quite capable of some modification but don't want to do a lot.
