On my 74 duster I unbolted the bumper shocks removed the brace in the bumper and bent up new brackets using 1/8 in steel. Bolted it back on using existing bolt holes. Saved about 80-100 lbs. If I remember right that was about 45 years ago
That makes sense. I know the steel metal brace behind the front of a Duster bumper is a little over 41lbs. The rear bumper steel brace must be a similar weight?
Either fabbing a smaller brace or just using a cutting disc to eliminate the 18’’ of steel brace that extends out from each end of the bumper mounts works. Also cutting/removing the 18’’ of steel bracing behind the license plate would probably cut a solid 25lbs from the rear brace while still using the small steel sections to actually hold the bumper to the shocks?
