'78 911SC Air Pump + AC removal - Follow up

Engine

Vehicle Information: Model: 911SC; Year: 1978; Body Type: Targa; Total Mileage: 53,000;

As a follow up to the air (smog) pump removal from my early SC, and if it may help anyone else, I found the small very hard-to-find "plugs" for the air injector holes at Weltmeister : part no. M10 x 1mm 900 219 010 02 X 6 required. It was quite tedious plugging all the various holes but now without the air pump and cats even this tired SC feels as if it gained 10-15% more HP. Again, thank you for the fantastic job you all do on these forums.
