Well, after lowering my '79 that old silver step bumper had to go. I checked several vendors and decided to go with the cheaper one from a vendor I like and trust. I was skeptical, but it fits great and was a nice complete kit. It came with brackets, bolts, bumper, license plate box and light. Complete bolt on package. As you can see from the pics below it looks great! The only odd thing about it is the bulbous chrome bumper bolts that look odd to me, but I kinda like them. I bolted it all together and it lined up perfectly.
The chrome is really nice, but the bumper itself is not perfectly smooth. There are small dents and wobbles. For the price though, I am very happy.
Bumper kit is from Truck Shop of Orange and it cost me $315 shipped to my door.
