Replacing intake manifold O-rings and gasket.

About a month ago I developed an issue of leaking coolant. Diagnosed as a bad intake manifold gasket I looked in two different manuals I have for step-by-step instructions to no avail. Next, I went online and still have found no real good instructions or best of all a good video of this procedure. The freezing cold weather seems to have subsided here in Maryland and I'm ready to begin this task.
Does anyone have a link to a video or can share an in-depth procedure for the replacement of the intake manifold gasket/o-rings on a 1980 RX7 / SA22C / 12A.
Thanks in advance.
