Crash Beam

74 duster was 1st year they had the 5 mph bumper ,suppose to spring in then back at 5mph with minimum damage, just put a 73 taillight panel on my 74, there was a small place at each spring for the beam support that the 73 didnt have, was going to remove beams on it , found out that 73 bumper braces had to be added , since all my under side braces and brackets were without rust, decided to leave mine as original.
