Yes it will be more than 3 inches. The springs will be mounted between the frame rails. I will be building new mounts to weld in for the front spring mounts. My dad is running a set up like this without the spring sliders on his 67' Dart. His is mini tubbed and he is running a 31x13 good year. Just a different way of doin things. My first thought was to weld mounts to the bottom side of the frame then bolt my sliders to that. Would have been quick and easy. I wouldn't have had to cut out my sheet metal in my trunk and move half my fuel system. I got to thinkin about it and decided I wanted to run the fattest tire possible with a mini tub. I also wanted to drop the car about an 1 1/2"-2" in the rear. The lower the rear is the easier the weight transfer. Plus I plan on running probably a 30" tire which is I think is an 1 1/2" larger than what I have on there now. With the way the car sits now a 2" drop will make it sit level. I have a lot goin on but I plan on posting pictures of everything. I suppose the thing to do would have been to do the build then post the pics and what not.
