my front bumper brackets on my 68 shelby gt500 are different than any other ones ive seen. the base that bolts to the frame is 11" where others are 8". this one has 4 holes instead of two. hear of such thing? it also has little oval pieces welded 3/4 way up shaft, others ive seen dont have them. the base looks as you can adjust front to back on the set of fours holes, lines up perfect.
