In reply to # 3535080 by Peter-Sherman The offset is in the body. Factory Jig .The body slews to the starboard side about half an inch so the axle appears shifted to the left. If you loosen up your U bolts and then retighten with leverage you can get a few mm. Hardly worth it but if you are just touching that might be just what you want. However you should not be touching. You will need new shackle bushes whatever you do. Because it is the shackle (which moves) you can use heavy duty ''race track'' or stiff bushes there. Use ''road going'' grade elsewhere unless you like a harsh ride. These are easy to swap over so that would make a good starting point. The most likely culprit unless you have not enough offset in your alloy wheels. What is your offset? Should be about an inch. It will be on the rim eg some variation on +25mm, 25mm pos etc
What a great hunting rig! Any idea what the chassis is??
