power steering box leaking from plates on top

I have a 71 dart, power steering box is leaking from the plates that bolt to the top. I am not sure Which plate is leaking yet. Sorry for not knowing what they are. Is it ok to remove them and check them for problems and maybe apply a thin layer of gasket sealer? Are there any gaskets that can be replaced? Never worked on a steering box until now. I just don't want to open up a can of worms if I do remove them. Is there anything I should be aware of?
