I am going to install a 9" lift on a 78 Bronco, what modifications do i need to make to the Bronco, besides a drop radius arm, drop pitman arm, brake lines, and drive shaft?

 

Black N Tan,
sorry, this isn't an answer to your question, but I have a soft cover, slant style tonneau, for that truck, if you are interested e-mail me at ginot99@ aol.com. It was only used 2 seasons, its in new condition and I made a custom track for the snaps out of an old hard top.

You may want to shim the rear diff up a little to offset the angle of the driveshaft. Don't go too much or you'll wind up with the pinion bearing running higher than the oil level. You may also want to lower the trans and transfer case a little to help with that also.
