Well-I had to cut/notch my late 70's frame to use an 81-up front bumper. I had read where people say you don't-but I can't see any other way. And, the 81-up frames have 2 holes for mounting the frame horn bumper reinforcement brackets whereas the 80-older only use 1 hole. I cut and notched my front framehorn sections to install the 81-up extension brackets and I'm also using 81-up bumper guards too. If I didn't do it the way I am, it would place the 81-up filler panel against the bumper and the edges of the bumper would sit too far beyond the fender side markers which would look stupid.
