A cheap way to get rid of weight is to take off the outer mounts. That will remove 7 pounds. I also cut about a pound out of each inner mount so thats 9 pounds less than stock. Now my front mounts only weigh 4 pounds.
that sounds like a good idea to remove weight, but how well does it hold the bumper now? is there any issues with flex or anything like that? especially on a bigger bumper like a 70 duster or 73-74 dart/scamp
