Do you still have the OME springs for the rear?
I'm lookin to go a similar route as Corey and stack my daystar spacer with these springs to hopefully level out the rear. I'm currently sitting at just over 38" (HD OME/RR 3/16" spacer) in the front and just under 37" in the rear (daystar spacer/ f-150 monroes). If it ends up givin to much rake I'll most likely just cut the front flares a bit to give a somewhat more level look. If you're wanting to get rid of you're old springs I'd be willing to buy 'em off ya.
