I am planning an IFS on my 60. My plan is a little unconventional. I am going to see if an Aerostar front can be made to fit. Looks like about an inch wider track and frame width. I'll know more when I get one here. Question is, stock centerline or move it ahead an inch? I always thought the 53-60 F100s looked like the front axle got pushed back and I'd like to "fix" that.
