Finally got the power steering done. Wow! I love it. Just wanted to report the 1977 wagonneer donor gearbox fit like a champ. I was even able to use the hoses with a little shortening of the return line. The pitman arm bolted right to my steering linkage after removing the large spacer washer that was between the stock arm and the linkage. My question is, is it okay to remove that washer? The waggy didn't have the washer and the casting of the power box's arm is thicker than the original manual box. Everything looks the same as far as fit and it seems great but then, I have a total of 1 mile seat time since the install and don't want to find out it's wrong while I'm driving.
