[vitamin c]

njsteve,
After recently doing the same rebuild to my 74 SD, I'm faced with the same problem of the left front being considerably higher, like 3/4 inch. After the front and rear springs were replaced I noticed the lean from behind the car and have traced it to the driver front spring. I used replacements #cs5402 from Classic and noticed right away they don't have the same tapered (flat) top coils as the originals. They look identical top to bottom, but they paint a white mark on one end and call that the "top" of the spring, and install "up". What I'm noticing is the driver spring is not sitting vertical in the frame spring pocket. The passenger side installed perfect and sits centered and vertical. Saturday I'm pulling the left front back apart to find the problem. My guess is that the sprint "top" is not siting in the correct groove in the frame. I used a bore scope to see up into the frame and see the spring doesn't look right. I'm assuming that the round replacement coils don't sit correct in the frame as original.
