When using Furd shock towers, does it take a different shock. Say I want to put Rancho 9012 shocks on my junk using the towers, does it take shocks for a GM or a Ford? Is the top mounting the same for the two? Sorry, second question, using that shock setup, would it matter on the axle being used( read: dana60 or 10 bolt) ? Or would it matter on the axle being that they would mount the same on the bottom. Any help would be appreciated. Trying to order parts but not sure on this one.
