Has anyone cut frame to move front bumper in tighter to body??

[64-454ss]

I've seen on 56-ish F$?d pickups where people will cut 2" out of front frame rails to move the bumper in tighter to body. Has anyone seen or done this on a 60-66?? It looks like I could move bumper in 2" and not have clearance issues. I'm thinking this would be a nice look. Also toyed with idea of a front roll pan. Any ideas or pics or comments would be appreciated.
