1976 Chevrolet Camaro - Project G/28 - Bye-Bye Disco Bumper!

The '70s were known for some pretty bad music, and some really awful Camaro bumpers. We can't fix the music, but there is hope for the bumpers!

Alan Johnson: "In this picture, you can see the two carriage bolts that hold the bumper to the impact absorber, which looks like a shock absorber. We eliminated these carriage bolts by making the bracket in next photo."

Alan Johnson: "That new bolt attaches the bracket to the top and bottom of the bumper instead of at the front. This allowed us to smooth the bumper and eliminate the bolts on the front. A word of caution: if you start welding or cutting with a torch on this impact absorber, it's filled with oil and it's under pressure, just like a shock absorber. Stuff's gonna go everywhere. This shows the new bracket that we made to bolt the bumper up. This picture shows a regular hex cap bolt. After we got everything fitted up, we counter-drilled the bumper and used countersunk bolts. That completely relocated the fasteners on the bumper to hide them. The bracket that holds the front bumper has a good deal of adjustment range from the factory, and all we did was max it out to pull the bumper into the body as much as possible."

Alan Johnson: "The back was pretty easy. All we had to do was countersink the eight holes in the bottom of the rear bumper (shown in the foreground). We took out the factory shims that go between the bumper and the bracket to pull the bumper into the body visually.

Alan Johnson: "Those holes you see in the body under the valence were slotted to raise the bumper up about three-quarters of an inch. We did the same thing on the front too."

Alan Johnson: "Here you can see how much we narrowed the front bumper, and how much we cut away front the end that wraps around. It's about an inch and a quarter on the width, and about an inch and three-quarters on the wrap-around. That's for each side. Once I was happy with that, I TIG welded it all together."

Alan Johnson: "Then I welded closed all the bolt holes. There was also a channel that the rub strip sat in, which we ground down. The bead that holds the rubber strip is about an eighth-inch high, and needs to be ground flat."

Alan Johnson: "The entire bumper is covered with a clear anodized coating. Before you weld on the bumper or paint it, you need to remove this coating. You can use an oven cleaner, or like we did, an air-conditioning coil cleaner for commercial air conditioning units."

This side view of the front bumper gives a sense of how much the bumper was pulled into the body, and how much the wrap-around was trimmed. Trimming the wrap-around is a necessity once you pull the bumper into the body, since the wrap-around sits into a recess.

Due to the limitations of the underlying steel reinforcement, no reshaping of the rear bumper was attempted. The bumper was shaved, smoother, lifted, and sucked into the boby within the range of factory adjustment (after all the spacer shims were removed between the inner bumper and the reinforcement).
