Replacing the Intake Manifold Gasket on 1990 Nissan Pickup (D21)

I need to replace my intake manifold gasket and was told all i had to do was take off some bolts with out removing hoses and wires. I just need to know if that is possible before i even try.

There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate
I have that and I have found no good images on the intake manifold. or on how to repair it. I don't know if I am looking at it wrong or what but I haven't found anything.

You may have to remove a hose or two but for the most part you only have to remove some bolts. Yes you can do this just remember to scrape all of the old gasket off and get the mating surface very clean before putting the new gasket in.
You wouldn't happen to have or know where i can get a diagram of the intake manifold. I looked in my repair manual and online but nothing is good enough for me to look at.
