You have a few options. Are you planning to put heat or A/C back in? If you are planning to put factory A/C back in, you will need the inside air box that houses the heater core along with the under hood evaporator cases and anything else the car is missing. If you just want heat, you can get a cover housing that eliminates the under hood evaporator case but you will still need the inside box (do a google search for A/C delete cover). If you plan to not have heat or A/C or you plan to go with an after market system like vintage air, you will need to make a metal cover to bolt or weld in place. You can also buy flat metal plate covers that will cover these openings, but it will be cheaper just to make something.
