After I did an SOA on my 40 with a 60 series front axle, I need to move my front spring shackle mount out 1" more. It was already outboarded 1.75" but, I had to move the axle perches out even more than when I had an SUA set up. Since it looks like I will have to make some type of frame box for the shackle mount, I could use some ideas. Thanks.
