You can buy the correct bracket @ EBAY , the Roseville guy has them. I found an original 70 bracket set on auction for $100 last year. They are lighter and only use two bolts to attach to the frame. The 1974 chrome fit, but only two bolts line up the top ones are for looks. Plus I removed the inner bumper for a 30# total savings. They adjust the bumper closer to the grill.
