Thought you might like to see what I did, instead of making (or buying) aluminum bumper brackets....
Done a lot of stuff like that over the years!! Also, hit every bolt you can. If it has extra threads showing, fix it. Anyone who has ever parted a car knows how many nuts and bolts a car has and how much weight they amass. I've even gun drilled non critical fasteners and used aluminum or plastic fasteners. Some of the critical fasteners like K-frame bolts were gun drilled using a smaller drill bit but considering their mass, going with a smaller bit probably wasn't needed. K frames get attention too. Several of y'all already know some of the things I do to get rid of excess weight....including punching holes everywhere that doesn't show.
bearman the factory front bumper and brackets weigh a ton on a 64 dodge. I spent a lot time to mill a factory set of bracket's down to almost nothing and sold them because they still weighed more than the aluminum one's that a friend built for me. you can get the weight down on your car but it's a lot of time consuming work and can be costly. I used many of dvw's tricks along with my own and others on here and moparts on my 330. I am not sure how correct the scale is at Norwalk. but I weighed my car with me in it said 3.386. without me 3.089. but keep in mind my car was a old school super stock car and the doors and fender's have been acid dipped with lexan side windows with no window regulators,glass hood, glass bumper. and a lot brackets and panels removed from the car. pretty much I have tried to lighten everything I could to reduce the total weight of the car. it can be done.
After I cut down my stock brackets I still used the stock bolts to mount the brackets to the frame but I used hardware store stainless steel Allen Head Cap Screws to mount my fiberglass bumpers to the cut down bumper brackets.
Carbon fiber.
I recently bought a pin on fiberglass hood and 5" hemi scoop from Glasstech. Cant beat their quality.
