'71 390 rear main seal

I'm getting ready to replace the rear main seal on my '71 F100 with a 390 in it.  I want to make sure my ducks are in a row before I start.  What I really would like to know is the steps to replace the seal.  I am using a neoprene type.  I know all the prep steps (jacking up the motor, removing the pan).  Also, the pins that come with the set for the cap side gaskets.  This may be a stupid question, but when you tap them in to seat the gaskets, do they stay in?  Finally, do I need any special tools?  Any help would be much appreciated.
