Which Truck Manual Do I Need?

[Harmon]

I have a 86 1/2 ton short bed chevy truck.  I want a manual for it and see them on another website, but some say light duty/heavy duty....I want to buy one but want to make sure I get the one that shows me electrical/interior and body info.....So my question is which manual?

Thanks.
