year of cab???

[kanuck]

I have started working on my project truck and am using a rust free cab from a donor that has no tag or anything on it. I know that it is 1981 to 1987 as it has the built in hood hinges but are there any other differences??? I know I might be getting myself into trouble as I ripped out the wiring harnass along with just about everything else so I can clean up the whole cab before paint but would like to know if I can take parts from any 81-87 to put it back together or if I need to find certain years. When I got it there was no dash, drip rails, dash pad, glovebox or much else inside, but the metal is absolutely spotless. Might have had a little work done on the drivers rear pillar as there are a couple of weld spots in the door opening but other then that it needs sanding and painting and then alot of assembly.
Thanks for any info.....
