I bought the ‘el cheapo’ fiberglass bumpers sold on ebay. Although I wouldn’t exactly call them cheap in dollars language. They fit decent, are very flimsy, look great (to me) when installed, install easy enough, and dang they are light weight!
Here is the weight difference on a very good medical scale.
Two stock 1980 Malibu bumpers with bumper guards and no belt trim along with four shock style mounts weigh in at 115 pounds.
Two glass bumpers with 1-1/2” roll bar tubing frame braces front and rear weigh in at 27 pounds.
This weight loss will offset some of what I added in the name of performance. Rear sway bar, heavier front sway bar, full 3” exhaust, and maybe a little more.
Here are pics of finished rear bumper and rear frame brace.
