I don't really know much about these...what you see is what you get. When I got King Springs for my 2004 L.L. Bean I was thinking I might add spacers at some point, Paul at Primitive told me if that was the case I would need these to get a good alignment. Never ended up using them...cost me $10/piece ($40 total).
So, make me a reasonable offer and they're yours...
