82/3 ea81 sedan carb swap and stuff removal

[Mykeys Toy]

I have done a weer swap but the car came equipped with most of the stuff for factory a.c. that I would like to keep for future reinstall what do I need to plug for the interim? Aaaand I have the exhaust tubes coming up from the heads and really don't know how exactly to plug them.. I can get pics if necessary I just don't have them now. Any help is appreciated since this project has taken far too long already.
