Slo-vo, couple questions:
Where are your shocks?! Are you using stock mounting locations with a rearch and shackle flip and still have enough travel? I'm figuring for mine to work, I'll have to set the upper mounts as high as the bed rail.
Also, how much of a re-arch did you do? I've been talking to a spring shop and they've been sayin that re-arching a 63" leaf pack to have 12" of free arch (4 to 5" over the stock arch of about 8") may not be possible...
