donor truck dilema

[a.c.1]

Hey all
I'm kinda new to this. Please correct me if my post is in the wrong location. I'm in the middle of my first attempt to rebuild a pickup. I've got a '68 shortwide tore down to frame right now. I recently came across an opportunity to purchase a dirt cheap, clean 86 short wide with a blown engine and trans. I'm undecide wether to use it as a donor or flip it. I'm pretty sure I can use the 5 lug disc/power brake system. Does anyone know if the 5 lug rear axles will slide into my '68 rear housing? What about the tilt steering column? I welcome any ideas that would drive me to tear this thing down for donor or fix and sell.
