Here is another ADDCO sway bar installation, compliments of Andrew Patrick (working on his MGA at the age of 16). Apparently he didn't want to drill another hole in his A-arm brackets and spring pans, so he made attachment brackets that connect to original spring pan bolts. He also includes a video of the installation process and Go-Pro camera view of the suspension in action during a rollicking good run on the road.
