i would not suggest coil overs on a DD..... The shock towers are not built for CO's. I would suggest you remove the front sway bar (rear optional). Install some 4cyl foxbody front springs (you can cut them a little). either keep the stock rear springs or go with a stiffer spring like a eibach. put a set of 90/10's in the front and a set of 50/50's in back. then a good set of uppers and lowers of your choice. then you should hook.
