I found a set of new bumper gaurds and need some help identifying the possible year. They almost match up on my 72 Cheyenne but have a little bit of a gap, shown where the red circles are. These have a smaller secondary indented area, below the main top ridge, where my older set is smooth. So, I believe these may be for 73 up? They both are stamped, on the back, with 914R
Can anyone help?
