Then it should have the mounts for both the standard brackets and the shock mount brackets in the front, and the earlier bumper brackets will bolt straight on.
This is a picture of my '74, which should match with the '74's made from December '73 through the end of the model year in July '74, and have all 3 mounting locations.
These are the other styles, although I screwed up with this one. The bottom one should be August '73 to December '73 ('74 model year) and 75+. 67-73 had the standard bracket mounts, August '73 - December '73 (ish) and 75+ should have just the shock mount, and December '73 (ish) through July '74 will have mounts for both the standard and the shock mount brackets.
