Temporarily removing factory A/C?

[Jonlopes]

My truck has factory AC but it does not work. Living in so cal getting the ac working is very far down the list of things to do. Unfortunately the AC set-up takes up a lot of room in the engine compartment and it sure would make my engine swap much easier if it was out of there.
is there anything I need to do to seal off and preserve the parts when I remove them or should I just keep them from getting dusty and not worry about it?
Does anyone sell caps to seal off the hoses going into the firewall?
