I unbolted and removed everything with NO cutting of anything, simply took an entire evening and carefully extracted ever component. This even included taking out the small condenser core inside the small box that resides inside the smugglers cubby hole. I retained the core housing and the internal fan so that I could still have additional air flow on those muggy days.
I had to make a small cover plate for the front condensers fresh air inlet that is behind the front bumper, and another slightly larger plate to fill the hole where the front condenser was. Simply bought some nice 1/8" thick black plastic and cut out the needed covers, used the factory screw holes to attach, a little clear silicone, and all is done.
My total system components weighed in at 53 !/2 lbs., although the massive underbelly condenser was a big contributor to all that weight.
Furthermore the big a/c lines do not really go thru the firewall, they simply pass behind the rear shock top towers and are sealed around the sheet metal with foam strips, you do not have to cut them to get them out, just a lot of patients and swearing gets the job done.
I did exactly the same thing, including keeping the front fan for some cabin air circulation if I get stuck at a stop light and need something to keep the heat down.

The only difference is that I used aluminum instead of plastic to cover all the holes in the front trunk, and sealed them with fiberglass glue.

My AC was more like 75 lbs, but it had two condensors and a sort of safety grille under the front of the car.

I got some lightweight aluminum crank/fan pulleys from Richard Clewett. I think not having the parasitic drag of a AC unit made a difference in how fast my engine spins up. The car felt different for sure, in a subtle way.

While I was at it, I removed every single piece of my windshield washing system and also installed a lightweight Deka battery. Now I have a huge amount of open space in my front trunk, instead of a cluttered mess since I don't carry the spare tire either.
