New Member, I have a question about a mustang II power steering I put on my 48 Chevy Truck. I used a chevy pump, I put the shims (3) like the instructions said. I drove about 40 miles and it started going all over the road, It was also to quick, I had to slow down to about 10 miles an hour to get home. I just returned the rack to get a new one, I don't now what to do next, can I put more shims in the valve, or what. Any advice would help. thanks Oldgezzer
