Bullnose all the way! i have a 1993 f250 4x4 that i will be putting the bullnose front clip on. I'm also putting 99 front/01 rear axles under it. I have a trac-bar kit specifically made for this conversion. You can get it here: https://www.skysoffroaddesign.com/pr...rd-apbsdac-001 And then I'm putting a carb 460 in it with a ZF 5-speed right now its just a body/chassis.

 

The more I look at them, I like the bull nose front end a little better esp when it has the impact strip and bumper guards, but the aero nose has a great deal of improvements since then. The brick nose is cool too but my least favorite.
