I was going to use them on that car but found a set of glass ones that are even lighter I am going to put on that car. So now they are on my Dart.
Outer mounts are about 3 1/2 pounds each. So not using them will save you 7 pounds right there.
Then cutting on the inner mounts I lost 1 pound per mount. They were 3 pounds each when I started.
You cant see it in the pics but I also cut some of the lip off of each side of the mounts but left a little bit of a lip an the part where the fender brace attaches to.
So right now the mounts on my 70 Dart are 4 pounds. Did this guy ever say what his aluminum mounts weigh?
