Kind of elementary, but.........I've got a P&J front end on my Model A, and one spring eye is a full inch lower than the other. Consequently, everything else is, too. What am I missing?
This is going to take some photos for anyone to be able to give you a solid answer. A few things are mismatched spring pearches, mismatched shackles. Spring is actually shorter on one side.
Have you tried tightening up the u bolt on that side to draw the spring up tighter on that side ? You can sometimes force the spring to shift the frame to one side or the other by loosening and tightening the u bolts. You may have to do it on the front and back to effect the amount of change you need. Don
Don is likely right as a first order of adjustment! Then use a 3' level if you can fit it in near enough to check the spring eye heights.
