I’m about to upgrade my 8 3/4 to a Dana in my Cuda. I’m going to go with a b body Dana and move the rear springs in a bit. The previous owner made the front spring mounts and welded them solid so before I go cutting I wouid like to check if their in the stock position or not and where to install the new ones. So if there’s anyone able/willing to do get some measurements I wouid be super grateful. In the pic I’m measureing from center of spring to centre of frame rail and I get 4 1/2”.
