I've heard it can be done but it puts the wheels out too far because of the difference in track width. The truck ends up looking out of proportion. The best way would be to install an aftermarket IFS that's engineered specifically for your truck. The 73 on up IFS do fit nicely under the 60-66 era trucks though,
