I’ve got an 88 1 ton truck, I am wanting to replace the current fenders with 4x4 fenders. Do I need to replace the inner fender as well? Also would I need to change corner lights and bumper? If so, will everything fit well.

 

Might be just the 90's era but.. Flip the marker lights over and swap sides to go from 2wd to 4wd styling.

 

just the inner splash guard .. mudflap would have to be custom , if you have them .
