Building a 69 Dart with a new passon 5 speed. The motor I'm hoping will be 600+hp my question is can I get away with the stock wheel wells and the offset spring hangers or should I mini tub and use the offset hangers? Or do I need to go all the way to moving the mounts in 3"? This isn't going to be a race car per say but I still would like it to hook up somewhat. I've already had my body man finesse the wheel well and roll the wheel lip so I've gained a little room. Thanks
