Questions about the Revell 1/72nd scale F-16A falcon

I was given the Revell 1/72nd scale F-16A falcon 1981 Model #4410 for a small price of $10.00. I really would like to build it as the XF-16A but I know the last time I built this kit I was a kid.
Now I would like to know,yes I know its an old kit, if I decide to use aftermarket detail sets to make this good kit into a great kit, what would be the AM sets that I would need to do this task?
Any and all comments and suggestions would be helpful, thank you.
