Finally put the new stock frame under the Merc. It has posies super slides and 4" blocks in the rear. I've seen other Mercs with the same combo, but, I cant figure out how they overcame the obvious scrubline problems. I really dont want to move the springs inboard. In the pics you can see that the springs themselves barely clear the scrubline without the bottom plate (I'll trim the u-bolts after I get everything where I want it & yes, the bottom plate is on backwards). Anybody have any tips or suggestions?
