I have a 75 2.0 I picked up last year. It was a great find. Beautiful white interior, AC and surprising not the usual rust. I took out the original drain plugs when I first go it. Under the rockers, is still clean bright original paint. The car was a garage queen with 47,000 miles and hadn't been ran since late 80's from the oil changes and registrations i found with the car. It's a twenty footer for paint, but just because dings and scraps, but once I used some rubbing compound on the white paint it came out real nice. The engine leaks oil from the usual spots, I'm going to do a complete resto in the future and have new Mahle pistons/cylinders waiting for that. That's the back ground. So with some time on my hands i replaced the AC dryer and seals I could find. I then put the 134 adaptors and charged it 134 oil to 2 1/2 pounds, went back and got it the car and low and behold nice cold AC. It was so exciting that it still worked. The compressor made some banging noise for a little while but that got quite after a few minutes. It may have to be rebuilt in the future, but for now it works. I'll try to post some pictures tonight, but I think I had a hard time with this sight last time because they needed to be smaller.
