My springs have been in the de-arching process for the last 60 years. :-)
Do you have pictures of your current stance??
I found this truck on the net and remember that is was not notched, but he commented that there was very little travel.
up front: 4" drop axle from sid, and I removed 3 leaves
out back: 6" drop mono-leaf from classic performance plus 3" lowering blocks.
That is pretty much the stance I am looking for!!
